Fluid-applied acrylic insulation coating
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.
Thermal Conductivity (ASTM C518 at 77°F): 0.0356 W/m-°K or 0.2468 BTU-in/ft²-hr-°F (R value at one inch equals 4.1)
Flame Spread (ASTM E84): Class A
Smoke Developed (ASTM E84): Class A
Tested in accordance with NORSOK M-501/ISO 20340
