POLYEURO 7502

Polyeuro^® 7502 is a fast setting, rapid curing, 100% solids, flexible, aliphatic, two component spray polyurea with excellent color retention.

 POLYEURO 7502 is a Two Component, Aliphatic, 100% Solids, Spray-Applied Polyurea Protective Coating.

PolyEuro 7502 is a fast-setting, rapid-curing, aliphatic polyurea protective coating designed for both interior and exterior surfaces. It is suitable for coating suitably prepared concrete, metal, steel, and other compatible substrates. The material offers outstanding color retention, making it ideal for environments exposed to UV and harsh conditions.

·       Component A and B (1:1 volume ratio): Mixed components form the reactive system.

·       This product may be used in combination with other Polycoat primers or systems as required by substrate and environmental conditions, although the TDS does not list a specific primer for PolyEuro 7502. A compatible primer should be chosen based on substrate per Polycoat's system recommendations.
