Aliphatic polyurethane acrylate
B-6210
Product features:
B-6210 is a polyurethane-acrylate resin containing two functional groups—hydroxyl and acrylate—that, when combined with an isocyanate compound, can be cured via a UV-thermal dual-curing process to form a functional coating. This resin features low viscosity, high curing speed, and produces a cured coating that is both hard and tough, with excellent chemical resistance. It also exhibits outstanding performance in environmental endurance tests, including high- and low-temperature cycling, impact resistance, and salt-spray testing.
