PLASTIC FIRE PROTECTIVE COATING

1. ALL SURFACES SHOULD BE CLEAN AND DRY. (NEW SURFACES SHOULD BE CLEANED  OF ALL MANUFACTURERS PROTECTIVE RESIDUES.  OLD METAL SHOULD BE CLEAN OF ALL OXIDATION.)

2. MIX ONLY THE MATERIAL THAT WILL BE USED WITHIN 3-4 HOUR PERIOD.  (MATERIAL THICKENS WITHIN 2-3 HOURS)  CAUTION - USE WITHIN ONE (1) HOUR IF SPRAYING !   DO NOT MIX FRESH MATERIAL AND PARTIALLY CURED MATERIAL - USE A NEW, OR THOROUGHLY CLEANED CONTAINER.   KEEP ALL CONTAINERS SEALED WHEN DIRECT ACCESS IS NOT REQUIRED.

3. MIX BY VOLUME:
  3. 5 PARTS - FX-PL ^™ COATING
  1 PART - T-50^™ CURING AGENT

NOTE: DO NOT MIX MORE THAN 1 PART (22.22)  "T-50^™ RESIN"  THIS WILL HINDER THE INTUMESCENT PROPERTIES.

FX-PL ^™ COATING (PART A) AND T-50™ CURING AGENT (PART B)  SHOULD BE MIXED THOROUGHLY WITH A MEDIUM SPEED, ROTATING MIXER.  THE MIXER SHOULD BE USED IN SUCH A WAY AS TO COMPLETELY BLEND THE TWO LIQUIDS, WHILE AVOIDING THE INTRODUCTION OF AIR INTO THE LIQUID.  THIS MEANS THE SPEED AND PITCH OF THE MIXER BLADES SHOULD NOT BE ALLOWED TO DRAW AIR DOWN THE CENTER INTO THE LIQUID, CREATING AIR BUBBLES WITHIN THE MIXTURE.

4. APPLY  FX-PL ^™ COATING  WITH A:
 BRUSH
 ROLLER
 SPRAY    (IF  A SPRAYING METHOD IS USED)  -  FOR GENERAL (OR ROUGH) APPLICATIONS, WE  SUGGEST USING AN AIRLESS, HIGH-PRESSURE PAINT SPRAYER WITH A #15-#17 NOZZLE.   FOR A FINE FINISH, USE HVLP (HIGH VOLUME LOW PRESSURE)  SPRAY EQUIPMENT.  IF PRODUCT IS  TOO THICK TO SPRAY IT MAY BE  HEATED TO  A MAXIMUM OF 100 DEGREES F.   A GOOD SPRAY  APPLICATION  TECHNIQUE IS NECESSARY TO PRODUCE AN EVEN FINISH AND AVOID DRIPS OR  RUNS.  (SEVERAL PASSES ARE RECOMMENDED).

6. TO ACHIEVE THICKER INTUMESCENT LEVELS (3-6”  CARBON FOAM LAYERING DURING  A BURN) APPLY GREATER THAN 10 MILS OF FX-PL ^™ COATING  TO SURFACE.

7.  FX-PL ^™ COATING  CAN BE APPLIED TO ALMOST ANY FULLY CURED COATING.

8. CLEAN UP FX-PL ^™ COATING  WITH HOT SOAPY WATER.

9. AFTER FX-PL ^™ COATING  HAS DRIED - COAT OVER WITH COMPATIBLE PAINT OR COATING  TO PROTECT FROM MOISTURE OR ABRASION.

MIXING
FX-PL ^™ COATING and T-50™ CURING AGENT  must be mixed in the ratios suggested by the manufacturer.

SPRAYING
After the FX-PL™COATING and T-50™CURING AGENT  are properly mixed, the product should be sprayed within 1-2 hours.  The product will begin to thicken after that time period.  This time varies with temperature and humidity, with humidity having the greatest effect.  (It takes longer to thicken if it is humid.)

If a thick coating is desired, it is best to apply FX-PL ^™ COATING in multiple coats, allowing the coating to dry to a tack between coats.

DRYING
This product dries by two methods at the same time.  (1) Water evaporates out of the coating, AND  (2) cross-linking takes place within the chemical when the two components are mixed together.  Drying can be accelerated by making changes that affect either, or both, of these aspects of FX-PL ^™ COATING drying process.

EVAPORATION:  Drying can be accelerated by (a) lowering the humidity, (b) moving the air (fans),  (c) raising the air temperature, or (d) exposing the coating to direct sunlight, UV or Infrared lamps.

CROSS-LINKING:  This aspect of the process can be accelerated by heating the FX-PL ^™ COATING  to 110°–150°F., while leaving the T-50™ CURING AGENT cool (70° - 80° F.), and mixing the two.  We recommend this only for those willing to experiment and LEARN the exact process that works for their particular situation.  This is because, if you use this method, the curing time can be greatly affected by each of the following:  (1) The temperature difference between the FX-PL ^™ COATING and the T-50™ CURING AGENT  , (2) the air temperature at the time of mixing and application, and (3) the humidity at the time of mixing and application.  (This warning is written because we have experienced cures so quick that a brush became stuck in a solidified 5 gallon pail of FX-PL ^™ COATING  in the “second” dip into the product.)  In that case, the FX-PL ^™ COATING  was over 160 F., and the T-50™ CURING AGENT  below 70 F.  The above temperature guidelines have been established to give you a starting point to discover an exacting method that works for your situation.

SURFACTANTS

If there is a problem with “beading”, “rolling off”, or “separating” on a surface, you can add 1-2% (maximum 5%) clear Ivory Liquid (concentrate) dishwashing soap.  This will break the surface tension and cause the coating to remain smooth and consistent.  FX-PL ™ COATING  is compatible with this soap, but if it is allowed to stand for a time, some of the Ivory will migrate to the top and must be mixed in again.  Again, REMEMBER, do not allow the mixer to cause foaming or draw air down into the mixture while blending!  This becomes even more critical when adding a surfactant (or in this case, a soap).

Application for ABS PLASTIC   test pieces that have passed UL Testing for UL 94VO Flame Test for MinnTech Corporation, MN were applied in the following method:

1.)  Plastic was clean and dry.

2.)  Mixed  FX-PL ™ COATING  3.5 parts with 1 part T-50™ CURING AGENT.

3.)  Sprayed at 35-40 PSI .   Appy a total of  3 coats, 2.5 mils wet each coat for a total of  7.5 mils finished  - dry 2.5 hours between coats (dry with ambient air, dry to touch, humidity 45-55 % - optimum.

4.)  Dried 3 days ambient air before using top coat.

5.)  Top-coated at  30 PSI,  1 mil wet.  Dried with ambient air for 12 hours.
