HardCoat Tech Data Sheet
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.
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 weatherresistant 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.
TECTECHNICAL APPLICATION DATA
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.
Adhesion Results of Typical Substrates per ASTM D-4541 Elcometer
Concrete- clean
>300 psi Concrete cohesive failure; excellent bonding
Steel- clean
>1000 psi Excellent bonding
Wood- dry/dust free >250 psi Wood failure; excellent bonding
Preparation of substrate surface prior to the application of any SprayEZ System
is extremely important to achieve proper system bonding.
If application surface ehibits extensive corrosion, normal forms of media
blasting is recommended to create a secure clean surface preparation.
Primers may also be required to obtain proper preparation. Always power
clean using mild detergent prior to ablating or sanding, etc.
