EPS HardCoat

EPS HardCoat

EPS HardCoat is an industrial abrasion resistant spray coating to be used over low density substrates such as polystrene foam and polyurethane foams which require exterior surface hardnesses up to 70 Shore D. It also provides excellent chemical and moisture resistance. This material is a two component 100% solids and contains no VOCs or solvents ot dissolve substrates. These specialized urea formulations deliver optimal curing application in very cold or hot climates. EPS HardCoat may also be used directly on clean primed metals, woods, fiberglass, concrete and masonary without the use of primers. Water-based primers may be used over typical foam substrates if desired.

HardCoat is normally applied by a 2K high pressure plural component pumping machine but may be applied low pressure cartridge systems. It becomes tack free in 15-30 sec with a 48 hour cure time to acquire its design hardness and wide functional temperature range from -20F to 150F. This durable and weather-resistant polyurea coating may be color pigmented and finishes to smooth surface. 

Please contact our technical support group for specific substrate application procedures, equipment, safety gear and clean-up kits. Refer to MSDS for material and safety standard procedures.

Application substrates must be clean/dry from contaminates; i.e. free of loose foam dust, rust flakes, oxidized paint, moisture, dirt, oils, etc. This material is to be applied within 40°F to 100°F. Mix B-side throughly prior to surface application if pigmented. Mix ratio is 1A:1B. High pressure spray machine: using Fusion gun 2200-2800 psi, Probler gun 1200-1800 psi. Apllication liquid temperature is normally set to 150°F. Recommended min. application film thickness is .040" (1mm). Coverage at 16 mils is 100 sq. ft./ mixed gal.
