High-temperature-resistant coatings are designed to withstand temperatures ranging from 150°C (300°F) to over 760°C (1,400°F) while providing protection against corrosion.
Composed of either organic or inorganic materials, high-temperature coating resins could either be an epoxy, epoxy phenolic, epoxy novolac, silicone, or a more specialized multi-polymeric matrix depending on the level of temperature resistance required.
For service under insulation, a single-component product like the PPG HI-TEMP 1027™ coating can be used for a wide range of operating temperatures and provides excellent protection against corrosion under insulation (CUI). In areas where insulation is not required, a two-coat system consisting of a primer and silicone topcoat is recommended.
