ALSAN TRAFIK PU 420 is a two-component, liquid applied aromatic polyurethane elastomeric topcoat. This topcoat provides excellent adhesion to SOPREMA polyurethane system base coats for application of SOPREMA polyurethane coating systems. ALSAN TRAFIK PU 420 is recommended for light and heavy-duty pedestrian and vehicular applications that are not exposed to ultra-violet light. When a topcoat is needed for UV exposure applications ALSAN TRAFIK PU 421 should be used.

Installation

Thoroughly mix ALSAN TRAFIK PU 420 Part A prior to combining. The volume mixing ratio is 5 gallons of Part A to 1/2 pint of Part B. Combined components should be mixed using a jiffy blade mixer at slow speed for at least 2 – 3 minutes. ALSAN TRAFIK PU 420 is applied to the approved area via roller, trowel or notched squeegee. The resin should be applied evenly onto the surface at a wet film thickness of 15 -20 mils (0.4 – 0.5 mm).
