Black Cat Catalyzed Waterborne Primer

Urethane Supply Company's Black Cat is the world's first catalyzed waterborne primer surfacer for plastic bumper refinishing. With the addition of the 3104 catalyst, Black Cat crosslinks for unmatched durability, flexibility, solvent resistance, and water resistance. The high-build acrylic formulation hides 180 grit sandscratches and is compatible with all automotive topcoat systems.

Benefits:

Coating crosslinks for unrivaled solvent resistance. May be wiped with lacquer thinner for over three minutes without disolving.
Once crosslinked, Black Cat Offers outstanding water and chemical resistance. If speed cured at 120° F for 30 minutes, Black Cat may be wet sanded in one hour. Black Cat will not bubble up or soften if inadvertently exposed to water after it has cured.
Black Cat crosslinks even at room temperature. May be wet sanded in 6 hours if not heated.
Outstanding flexibility and adhesion even at cold temperatures. Black Cat does not crack even when flexed over a 2 inch radius at 25° F, even when sprayed over an unsanded OEM clearcoat finish.
High build formulation fills 180 grit sandscratches easily. Excellent dry sandability, and unlike other waterborne primers, it can be wet sanded as well.

Application:

Prepare surface by cleaning and sanding with 180-240 grit paper.
Mix 3103 catalyst 2% by weight with primer. Catalyst labels include markings for approximate volume of catalyst required. Catalyst leve can vary between 2-3% by weight without negative impact on coating properties. Water may be added up to 5% by volume for a smoother finish.
Spray with HVLP gravity gun using 1.7 - 2.0 mm nozzle setup.
Speed cure at 120°F for 30 minutes. Crosslinking reaction will occur in six hours at 72°F.
Pot life of catalyzed primer is 90 minutes at 72°F. Clean gun first with water, then with acetone.
