Product Description

Sherwin Williams Heat-Flex Hi-Temp 1200 is the next generation single component inert multi-polymeric matrix coating that outperforms alternatives in combating corrosion under insulation (CUI) and in high heat applications.

Best Uses

Sherwin Williams Heat-Flex Hi-Temp 1200 recommended uses include applying direct to steel or stainless steel, as a coating under insulation, for cyclic service up to 649°C, acceptable for use on cryogenic equipment, for use over properly prepared steel surfaces, either insulated or uninsulated.

Areas of application include: Power Plants, Refineries, Chemical Facilities, Offshore/Marine, Pulp and Paper. Benefits include: Resists corrosion under insulation, Resists stress corrosion cracking, Application surface temperatures from ambient to 260°C, Operating surface temperatures cryogenic to 649°C, Heat curing not required to cure and provide corrosion resistance, Self priming, single component, No maximum recoat time.


Prepare stainless steel or carbon steel to SSPC-SP10. Surface must be clean, dry, and in sound condition. Remove all oil, dust, grease, dirt, loose rust, and other foreign material to ensure adequate adhesion. When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at a right angle. See data sheets for in depth info.
