Series 1558

Endura-Heat DTM

Generic Type

Modified Silicone Copolymer

Common Usage

A versatile silicone copolymer coating applied direct-to-metal (DTM) or as a topcoat in high-temperature coating systems. Its high-build characteristics and corrosion-inhibitive pigments provide protection to steel substrates up to 1000°F (538°C). Wide color options and superior adhesion to marginally prepared substrates make it an excellent choice for use throughout refineries, power plants, petrochemical facilities, and treatment plants. Requires a 350°F (177°C) heat cure prior to placing in service.
