| Waste Disposal Methods: | In liquid form, these resins are considered ”hazardous waste” as the term is defined in the Resource Conservation Recovery Act (RCRA, 40 CFR 261, Identification and Listing of Hazardous Waste, due to its characteristic of ignitability (alcohol content). As such, disposal of liquid via incineration is required by regulation. However, in many areas, reacting the T50™-TB curing agent with FX (FSTB) resins first, to produce an non-toxic, non-flammable solid followed by disposal as a non-hazardous solid waste may be acceptable. Disposal should be in accordance with all applicable, local, state, and federal laws and regulations. Consult your attorney or appropriate regulatory officials for information on your locality. | ||

| Health Effects Summary: | Although the raw materials from Ineos Melamines which are mixed together to make T50™-TB are reported to be “Practically Non-Toxic” and “Practically Non-Irritating”, they do contain very small quantities of Isopropyl Alcohol (< 5.1%) and Formaldehyde (<1.1%) as used. In pure form these chemicals present moderate to substantial risks to health and safety, but the low concentration levels in T50™-TB reduce this to proven levels of safety if handled with appropriate precautions. For the information of the user, details regarding dangers of these individual materials are included for reference in case of severe over-exposure to the product and in case of emergency or fire. Following are excerpts of information provided by INEOS MELAMINES regarding some of these components: FORMALDEHYDE In addition to the irritation effect to the eyes, nasal passages, respiratory tract and skin, formaldehyde solutions can produce allergic skin reactions. Numerous publications in the scientific literature confirm the irritating properties of acute and short-term exposure to formaldehyde in humans and animals and discuss toxic effects which are probably related to the irritants properties of this chemical. Formaldehyde is listed as a substance that “may reasonably be anticipated to be carcinogenic” by the National Toxicology Program (NTP) in their Fifth Annual Report on Carcinogens, is classified as “probably carcinogenic to humans” by the International Agency for Research in Cancer (IARC Monographs, Vol. 29) and is regulated by OSHA as a carcinogen (29 CFR 1910.1048). The NTP and IARC listings were based, in part, on their determination that there is limited evidence for the carcinogenicity of formaldehyde in humans. However, the largest study (with a study population greater that the total of all other studies - more than 25,000 workers) found little evidence that mortality from cancer is associated with formaldehyde exposure at levels experienced by workers in the study. The NTP and IARC also considered that there is sufficient evidence for the carcinogenicity of formaldehyde in experimental animals on the basis of studies in which nasal tumors were formed in rats and mice following chronic exposure to formaldehyde. Formaldehyde produced genetic changes in a variety of standard tests. “Pure” formaldehyde has an oral (rat) LD50 toxicity level of 100 mg/kg. The dermal LD50 in rabbits is 270 mg/kg, and LC50 following a 4 hour inhalation exposure to rats is 250-478 ppm. Exposure to formaldehyde vapor at concentrations in excess of 1 ppm may cause significant irritation of the eyes and respiratory tract. The irritation threshold appears to be 0.3 ppm. No pulmonary sensitization has been demonstrated in laboratory studies. Formaldehyde solutions can cause severe eye and moderate skin irritation. Repeated skin exposure to solutions of 2% or more formaldehyde has caused allergic skin reactions. Formaldehyde was found to be weakly active in a number of in vitro genotoxicity test, but inactive in vivo. Formaldehyde did not cause birth defects in rats inhaling concentrations up to 10 ppm. Lifetime inhalation of formaldehyde vapor at concentrations above 5 ppm for 6 hours per day, caused nasal tumors in laboratory animals. Many epidemiology studies have failed to link cancer in humans with occupational exposure to formaldehyde. | ||

Return to Service means dry to touch and moderate contact. CURE TIME is 48 hours or more.
NOTE: There are three phases: Return to Service (OK for contact), Cure Time (dry 100% solid), Fully cured (washable).
*MAX Humidity during APPLICATION = 85%. During the CURE PERIOD, Humidity must not exceed 85% more than 4 hours / day. If such occurs on any given day, the cure period must be extended by 24 hours.
Washing
Flame Seal-TB™ has cured enough to be cleaned after 3 months of curing under proper conditions as stipulated in these instructions (all surfaces at least 5° above the dew point, with good ventilation & air movement at all times.) This may take longer with variations in dew point conditions. To clean, use light to moderate pressure tap water sprayed through a dispersion tip with a wide spray pattern. The spray pattern must be at least 24” wide and must be moving at all times. DO NOT FOCUS ON ONE SPOT FOR MORE THAN A FEW SECONDS AT A TIME. If heavy dirt does not come off with the spray alone, then use the spray method first to remove loose dirt, then wipe stubborn areas with wet sponge or similar type apparatus, then, rinse again with tap water spray. Let the surface air dry. (Do not dry with cloth or sponges.) If there is a need to force a quicker dry, use warm, dry moving air (convection).
IMPORTANT NOTE: DO NOT CLEAN WITH CONCENTRATED HOSE STREAM, FOCUSED NOZZLES, HIGH PRESSURE WASHERS, HOT WATER OR STEAM CLEANERS.
In-Service Requirements
WATER EXPOSURE
Flame Seal-TB™ is an interior product. DO NOT immerse or expose to any environment in which the surface is wet continuously. (This includes condensation caused by interior conditions whereby surfaces temperatures are at or below the Dew Point much of the time.) Occasional exposure to moisture (including cleaning procedures) is allowed.
NOTE: CONDITIONS THAT MAY KEEP SURFACES WET CONTINUOUSLY REQUIRE A WEATHER PROOF TOP COAT TO BE APPLIED OVER THE FLAME SEAL-TB™.
VENTILATION
Flame Seal-TB™ may be applied on SPUF insulation in any interior space, so long as there is a ventilation system in place (HVAC, power ventilators, turbines, ridge vents, gable vents, attic fan, etc.).
**FOR “QUALIFIED” APPLICATORS & EXPANDED WARRANTY: Applicators must make sure the coated area maintains ventilation that meets the requirements of Chapter 4 of the International Mechanical Code (IMC), in accord with acceptable building practices. If it is unclear which IMC code applies, Flame Seal Products’ default (minimum) requirement is 0.12 CFM/FT².
AIR MOVEMENT DURING APPLICATION & CURE
To facilitate a proper cure, there must be air movement in the application area during the application and cure period. In mid-to-high humidity conditions (65% - 80%), extra care must be taken to ensure there is detectable air movement, especially over all ceiling SPUF surfaces during the application AND curing period. Air at the ceiling that is absolutely STILL OR STAGNANT is not permissible. If any areas are doubtful, portable auxiliary fans should be used during application and cure periods to assure air movement.
**HIGH HUMIDITY / MOISTURE CONDITIONS (Only for Level Three applicators):
When applying Flame Seal-TB™ in areas with “borderline” high humidity (85%+) conditions during application and curing (examples: ceilings directly over equipment that generates steam that is not fully vented, or ceilings over anything that generates a high volume of water vapor): In addition to the above requirements, a good quality humidity meter must be used to monitor RH levels throughout the application and cure period. Also, there must be high volume, continuous air movement that will visibly move a 1” x 18” strip of cotton fabric held vertically near the ceiling. Check this in several locations. (In other words, there must be strong air movement in all areas of the surface to be sprayed.) Auxiliary fans may need to be placed in the work area during application and cure periods. If dew point is borderline, auxiliary heaters or de-humidifiers may need to be employed to assure a good cure. (NOTE: The planned procedures for these extreme job conditions must be approved by Flame Seal Products, Inc. before proceeding to maintain manufacture’s warranties.)
**FREEZING - FOR “QUALIFIED” APPLICATORS ONLY (+ EXPANDED WARRANTY.)
Flame Seal-TB™ may be applied in cold storage or freezer units ONLY by a “Qualified Applicator” who has completed Flame Seal’s LEVEL THREE Qualified Applicator Training Program.
If Flame Seal-TB™ is applied in areas that will freeze (inside freezer units), the product must be allowed to fully cure FOR A MINIMUM OF 4 DAYS in accord with these Instructions: SPF surface temperatures must be between 60°F - 90°F. Air temperatures must be between 50°F - 90°F. The application must cease if any of these temperatures do not remain within these ranges. Maintain APPLICATION LEVEL ventilation & air movement, zero water exposure, and Always Follow the Dew Point rule:
“In accord with commonly accepted coating practices, the foam *SURFACE temperature must be at least 5°F above the Dew Point during application, as well as during the cure period. (See attached “Dew Point Calculation Chart”).”
**DO NOT ALLOW THE COATED SURFACES TO FREEZE PRIOR TO THE END OF THIS CURE PERIOD, OR WITHOUT ADHERING TO THESE REQUIRED CONDITIONS.
**NOTICE: For Freezers that will experience “warm / freeze” cycles on a regular basis, the above cure period must be extended to 7 days.
**WARNING: THE CLIENT MUST BE NOTIFIED THAT ANY “WARM/FREEZE” PROCESS MUST NOT INCLUDE WARMING BY OPENING DOORS TO EXPOSE THE SPACE TO OUTSIDE AIR, AS THIS CAN CREATE EXCESSIVE CONDENSATION. ELECTRIC OR VENTED GAS HEATERS MUST BE USED AS THE SPECIFIED PROCEDURE FOR WARMING A FREEZER UNIT.
Coverage Rates
- Thermal Barrier - Applied at 25 wet mils (18 dry mils):
- Coverage of 65 sq. ft. per gallon or 1.6 gallons per 100 sq. ft. on foam with average, moderately smooth surface profile*
- Cross linked Flame Seal-TB™ is formulated to hang on a vertical surface @ 25 mils. More than 25 mils may cause product to sag, less than 25 mils may not hide the foam surface color.
NOTICE: For Thermal Barrier applications on 0.5 lb open cell SPF insulation, the recommended coverage rate is 30 wet mils, in accord with test results. This equates to 21 dry mils, 54 sq. ft. per gallon, or 1.85 gallons per 100 sq. ft. on foam with an average, moderately smooth surface profile*
- Ignition Barrier – Applied at 4-12 wet mils (3-7 dry mils), depending on the SPF brand
(See >NOTE):
- Coverage of 125 sq. ft. per gallon or 0.64 gallons per 100 sq. ft. on foam with average, smooth surface profile*
* Rough foam surfaces will require more product and should be accounted for when calculating the amount of needed material.
>NOTE: Coverage rates vary with each SPF manufacturer’s test reports. At the time of this writing, the range of specified coating thickness for Ignition Barrier work is 4-12 wet mils.
Application Equipment Requirements
IMPORTANT NOTE: Flame Seal-TB™ is a specialized fire protection coating, and is NOT a paint! EVERY component of Flame Seal-TB™ is a Fire Retardant, and contains NO flammable latex binders (that’s why it is so superior!). As a result, it is a LOW pH coating, and will react with any HIGH pH material. (MOST paints are HIGH pH.) THEREFORE, we recommend dedicated spray guns, hoses and pump* for “perfect” results every time. If not feasible, then extra care must be taken to THOROUGHLY clean the spray equipment (guns, hoses and pumps) to remove ALL contaminants (high pH) such as latex or other coatings. IF YOU DO NOT DO THIS, FLAME SEAL-TB™ MIGHT SOFTEN AND LOOSEN OLD RESIDUES INSIDE THE SYSTEM, WHICH CAN CAUSE CLOGGING OF YOUR SPRAY GUN. (The Flame Seal-TB™ is, in effect, trying to “clean” out your system)
Most common airless paint equipment will work with Flame Seal-TB™. The size and power of the spray equipment is determined by the size of the job and total length of hoses.
The minimum requirements: (this will work well, but only for small jobs, as the pace will be slow)
- 3/4 HP Electric Motor (or)
- 1 HP Gas powered
- Output capability of 0.4 gallons per minute with 2000+ PSI (dynamic) at the gun
- RAC tip size .021 - .031 - determined by paint pump capability and desired spray pattern.
NOTE: Do not use a spray tip with a diffuser. Remove paint strainers from the spray pump and gun, as they may restrict the flow of Flame Seal product. Flame Seal-TB™ is pre-strained through an 80 mesh filter.
*If you cannot dedicate a pump to this product, make sure it is as clean as possible every time you use your dedicated guns and hoses!
RECOMMENDED PERSONAL PROTECTIVE EQUIPMENT (PPE):
- A “Fresh Air System” is recommended for applications in areas without adequate ventilation
- An Organic Vapor Cartridge Respirator is recommended for applications in well ventilated areas i.e., 3M-5201 Organic Vapor Assembly
- Safety Glasses
- Gloves
- Protective Coveralls
Application Procedures
Conditions to Proceed with Application
Before beginning an application, make sure the conditions meet all requirements of these INSTRUCTIONS, as:
- All surfaces to be coated are clean and dry.
- All equipment for application and clean-up is on site, and as specified in these instructions.
- The Temperature of all Flame Seal-TB™ and T50-TB™ to be used is between 60° - 80°F.
- The Temperature of all surfaces to be coated is at least 5°F ABOVE the dew point (see attached chart).
- MAXIMUM HUMIDITY AT THE TIME OF APPLICATON = 85%
- The above temperatures, including coating components and surfaces will remain in spec throughout the day.
- The surfaces will remain at least 5°F above the dew point for a minimum of 48 hours after application.
**NOTE: For Freezers / Freeze applications, this period will be 4-7 days. (See “FREEZING” section) - The spray area meets minimum ventilation and air movement in accord with these instructions.
*If application is in high humidity area, additional air movement is required.
See “AIR MOVEMENT” section.
Blending and Mixing Procedures
Prior to starting the mixing and blending process, Flame Seal-TB™ components must be a minimum temperature of 60°F and maximum 90⁰F. SPF surface temperatures must also be between 60°F - 90°F. Air temperatures must be between 50°F - 90°F. The application must cease if any of these temperatures do not remain within these ranges. Always Follow the Dew Point rule:
“In accord with commonly accepted coating practices, the “Foam *SURFACE Temperature” must be at least 5°F above the Dew Point during application, as well as during the cure period. (See attached “Dew Point Calculation Chart”).”
Upon opening the Flame Seal-TB™ resin container, you may notice a spongy top layer. This is normal, and will mix into the liquid easily.
- Mix Flame Seal-TB™ resin thoroughly until mixture is homogenous - until there are no spongy pieces larger than ¼” diameter, and the mix looks smooth. DO NOT DRAW EXCESSIVE AIR INTO THE MIX, AS BUBBLES MAY CAUSE PROBLEMS WHEN SPRAYING. (Use an “aggressive” drill mixer, designed for 5 gallon pails, with a ½” chuck drill motor and mix at 600
– 800 rpm. Spin in direction that pulls the liquid UP. DO NOT use a cordless drill motor.)
- Shake the one gallon jug of T50-TB™ Cross Linker for a few seconds prior to adding to the Resin. The T50-TB™ may be slightly thicker near the bottom of pail, so be sure to do this. (Unless it is being used (poured), T50-TB™ must always be kept sealed.)
- Add the T50-TB™ Cross Linker to the resin and mix with the same mixer used in step #1. Mix for approximately one minute, or until thoroughly mixed. Avoid drawing air into the mixture while stirring. T50-TB™ Cross Linker adds instant viscosity and body to the mixture. Once the Cross Linker is added and mixed in, the mixture’s pot life begins. DO NOT stir or mix further as it may shorten the pot life of the mixture. (NOTE: If the mixture is left still for a time, and spraying becomes difficult, stir or agitate for a few seconds to restore proper viscosity for continued spraying.)
*NOTE: It is crucial that the mixture is not under mixed, which could result in an uneven mixture, causing incomplete curing in some areas.
- Verify the mixture temperature with a thermometer. The temperature of the mixture will determine pot-life as indicated on the resin pail label.
Application Procedures
Spray Application:
Spray in a cross hatch pattern to achieve 25 wet mils coverage on vertical surfaces. 25 wet mils (.017 - .018) coverage will provide a 15 minute thermal barrier. 12 wet mils (.007 - .008) coverage will provide an ignition barrier.
- An ignition barrier application requires one coat of 4-12 mils. (depending on the Brand and tests)
- A thermal barrier application requires one 25 mil coat on vertical surfaces. Ceilings require two thin coats that add up to 25 wet mils. (Ex: First coat = 10 mils, Second coat = 15 mils).
NOTE: Product is designed to ‘hang’ on a vertical surface at 25 wet mils. Anything greater than 25 wet mils may sag or run.
Roller Application:
- Vertical surfaces: Apply in two coats using 3/8” nap roller. Allow 6 – 10 hours dry time between coats.
- Overhead surfaces: Apply in two coats using 3/8” nap roller. Allow 6 – 10 hours dry time between coats.
*NOTE: Roller application of Flame Seal-TB™ is difficult and is not recommended. Whenever possible, apply with airless spray equipment. Manufacturer recommends roller application only for small jobs or difficult to reach areas where spraying would be difficult, or overspray would be a problem.
Spray Equipment Cleaning Procedures
After each use, you can clean the equipment quickly and easily with HOT SOAPY WATER as follows:
- Use a 1 tablespoon of non-Ionic soap such as DawnÒ detergent in 4-5 gallons of hot water.
- Use water from a hot water tap. (at least 110 degrees F for best results)
- Use a standard or infrared thermometer to verify water temperature.
- Flush out the pump system, hoses and guns until water runs clear.
Note: If a water heater is not available, and water is cold, it is best to heat 2-3 gallons of water to get the equipment well cleaned. If only COLD water is available, it is recommended that the cleaning procedure should be followed with cold water, leaving the equipment full of clean water… then; a hot soapy water flush must be performed upon return to the Contractor’s facility to get maximum cleaning of the equipment.

FAQs
Flame Seal-TB™ Fire Retardant Coating FAQs
What is Flame Seal-TB Fire Retardant?
Flame Seal-TB is a fire retardant coating designed for use over spray applied polyurethane insulation.
Flame Seal-TB is a water-based resin that is combined with a cross-linker to form a powerful intumescent coating.
Flame Seal-TB has multiple ICC Certifications over various Spray Foam brands as both a Thermal and an Ignition Barrier.
Why is Flame Seal-TB a two component product?
Flame Seal-TB is the most powerful low temperature intumescent coating in the world. That is because, in the development of Flame Seal-TB, Flame Seal Products decided to use only raw materials that are inherently fire retardant chemicals to begin with. This made the project much more difficult, but it is the reason for the extreme level of intumescent performance. No compromise.
No other coating or paint can match the performance of Flame Seal-TB, because other products use one or more flammable components, such as latex to allow the coating to cure, and to give it good surface properties. Therefore, the fire resistant properties of other coatings must first defeat the flammability of all those components, before addressing the protection of the substrate (foam). In the case of latex paints, the latex itself is inherently quite flammable, so the coating must first deal with the negative effect of the latex on the overall performance (there is less chemical action available to protect the SPUF).
Flame Seal-TB does not have that problem. Since every component is a Fire Retardant chemical, when a fire occurs, the coating is 100% devoted to protecting the substrate (SPF). This has a doubled effect as far as improving performance. If 20% of a coating has latex, that is 20% less fire resistance. That means it is 80% as effective as Flame Seal-TB. Their 80% effectiveness must then defeat the latex component, which uses a portion of the fire retardant effect of that 80%. Thus, if that is another 20%, the latex based product is down another 16%, resulting in a coating that is only 64% as effective as a product made from 100% fire retardant materials (Flame Seal-TB). This happens to be about how superior Flame Seal-TB actually is, and this is the primary reason for this.
Why does Flame Seal-TB have a *low pH (acidic), whereas most paints have a high pH (alkaline)?
Since almost all major fire retardant chemicals are acidic in nature (low pH), it stands to reason that a truly “dedicated” or “specialized” coating designed purely for fire protection performance, would have a low pH.
It is important to understand that Flame Seal-TB is not paint. It is a specially formulated safety coating for fire protection. That is why it has a “special” pH range. That is also why it is a two part system. It reacts with itself to form a strong coating, so it won’t need a binder like latex to hold it together. That is why it performs at a level unmatched by paints or latexes. Finally, this is why we do not switch to a latex, one part, system. It would be inferior.
What is the best way to handle the spray equipment?
Considering these facts, it is advised that if you want perfect results every time, use specifically dedicated equipment for this purpose (or equipment that has been thoroughly cleaned with an “acidic” cleaning liquid).
The pH difference is the reason Flame Seal-TB reacts with any residual material from other paints or coatings, if such remain in the spray equipment, and essentially “cleans out” those residual contaminants. The problem is, if such is the case, the cleaning process will cause loose particles to clog the spray gun during the first 1-5 gallons of spraying, thus wasting material. This is why dedicated equipment is advised so as to avoid any chance of having problems.
Can we “thin” Flame Seal-TB (other products allow this)?
You must not thin or alter Flame Seal-TB in any way. This is a safety product that has passed extremely strict test requirements and the coating must be used exactly as tested to assure the application meets code requirements. Beware of any company that says you can thin their product, unless their ICC certification and test lab report states that the product passed tests in a “thinned version”. Otherwise, you may find you are not covered in the event of a fire occurrence!
Can we “top coat” Flame Seal-TB (other products allow this)?
Similar to thinning issues, Flame Seal-TB must not be top coated with another product without consent from the manufacturer. Flame Seal Products, Inc. has tested most available latex paints and found that the vast majority of these products inhibit fire performance. There are only a very few that do not have a negative effect and they are the only ones approved by Flame Seal Products. Do not apply a top coat over Flame Seal-TB without written approval and instructions from Flame Seal Products. Further, if any manufacturer states that you can apply “any” paint over their product, such practice may leave the user without actual protection in a fire event.
Is Flame Seal-TB available in colors other than white?
Flame Seal-TB is available in white, light gray, medium gray, dark gray and black at the present time. A full spectrum of colors will be tested and available in the near future.
Is this coating washable (latex FR coatings are not)?
While it is known that latex based intumescent coatings cannot be washed, Flame Seal-TB is not a latex product and does cure to a smooth, semi-gloss, washable surface. The cure conditions and cure period must be followed before washing, with limitations as: power washers, steam cleaners, jet wash systems, and hot water. The system is easily cleaned with moderate pressure cold water spray, and includes light scrubbing per instructions provided by Flame Seal Products, Inc.
What are other advantages of using Flame Seal-TB?
Ease of use: this product takes only a minute to mix (literally) and is then ready to spray. The texture and viscosity are very easy to work with, providing you use dedicated equipment or are very conscientious about keeping the spray equipment clean.
Dependability: Flame Seal-TB has never failed a single Thermal Barrier test on Closed Cell foam, which demonstrates the reliable nature of the product, the manufacturer and the integrity of both.
Quality: Flame Seal Products uses a Boeing Aerospace Quality Control Process, which maintains meticulous control over the manufacture and packaging of its products. Flame Seal Products has never had a failure due to product defect in its history (Flame Seal Products first began selling to the public in 1992).
