Thermaline 440 (formerly Thermaline 400 EU) is a high performance, heat resistant epoxy phenolic that specializes in providing color for uninsulated piping and equipment. This immersion-grade coating which has excellent resistance to wet/dry cycling conditions at elevated temperatures when using dry grind pigments. This formulation allows for use on hot steel substrates under insulation operating continuously up to 204ºC (400°F). It has excellent chemical resistance properties to handle the corrosive effects of wet insulation under thermal cycling conditions.
