Series 1528

Endura-Heat DTM

Generic Type

Inert Multipolymeric Matrix

Common Usage

An advanced, inert multipolymeric chemistry that provides high-performance direct-to-metal (DTM) coating protection to steel and stainless steel substrates in elevated temperatures up to 1200°F (648°C). Exceptional adhesion properties allow the coating to withstand severe thermal cycling (-300 to 1200°F), and its tolerance to marginally prepared substrates make it a viable alternative when abrasive blasting is not permitted. Its high-build feature and resistance to cyclic conditions make it an excellent coating system on pitted steel and for protecting against corrosion under insulation (CUI). Dry-fall spray characteristic provides fast, labor-saving coating application when used with appropriate thinner.

Special Qualifications

Meets NACE SP0198-10 requirements SS-4, SS-5, CS-6 and CS-8.
