B-274/AS-P108 Black KIT

B274-ASP108 is a two-component, room-temperature curing polyurethane elastomer designed as a rain erosion coating. Supplied as a 1 US gallon kit (black), it protects radomes, antennas, and leading edges, resisting high-speed rain impact and reducing static charge accumulation. B274-ASP108 combines a high-performance polyurethane elastomer base with a compatible curing component to form a tough, flexible erosion-resistant film. Engineered for aerospace and high-speed applications, the coating bonds well to typical substrate materials and cures at ambient temperatures. It can be applied by pressure or suction spray equipment and is optimized for target thicknesses in the 11–13 mil (0.28–0.33 mm) range to balance erosion protection and aerodynamic smoothness. Fast cure characteristics enable full thickness application within six hours under recommended conditions.
