Series 971 | Aerolon Acrylic

Generic Type Fluid-applied acrylic insulation coating
Common Usage An innovative, fluid-applied, thermal insulating coating utilizing aerogel particles that imparts exceptional insulative properties to a variety of substrates. Ideal for insulating pipes, valves, tanks, structural steel, or other substrates where thermal improvement or personnel protection is desired. Part of a durable, corrosion-resistant coating system that bonds to the substrate, greatly reducing the issues associated with corrosion under insulation (CUI) and mitigating thermal bridging by controlling condensation.
Colors 1278 Insulation Yellow, WH13 White.
