POLYESTER POWDER COATING • Transportation Gray 6334 • 1PC-107-9145
The Transportation Gray 6334 is a full gloss, smooth finish in a medium gray color. This formulation was originally manufactured to the specifications provided by an OEM for use on electrical cabinets inside of train compartments.
The powder coating can be used on any properly prepared metal. It has great UV (sunlight) and weather resistance, so it works for exterior exposures. The finish has good chemical resistance.
What makes this product different is the strict testing it has passed to be used inside of passenger compartments on trains and buses. The tests listed below are used to evaluate the safe exit time for humans in case of fire given how the powder coating can react with heat.
ASTM E 662-13b Smoke Density Test
ASTM E 162-2012a Surface Flammability from Radiant Heat
Boeing BSS 7238 Smoke Generation by Materials on Combustion
Boeing BSS 7239 Toxic Gas Generation by Materials on Combustion
The testing was performed by a 3rd party lab with strict adherence to test protocols. The coating met or exceeded all measures as outlined in the specification.
FORREST Technical Coatings has been manufacturing this powder for several years. It has been used on parts installed on hundreds of train cars and train engines.
