High-temperature coatings are engineered to safeguard materials from the damaging effects of temperatures ranging from 150°C (300°F) to 760°C (1400°F).
They are recommended in situations where materials require protection from corrosion as well as heat. If a greater degree of heat resistance is demanded by a particular application, specialized treatments and formulations can provide enhanced protection. High-temperature coatings can be formulated using both organic and inorganic compounds, including:
- Epoxy phenolics
- Epoxy novolacs
- Multi-polymeric substances
The exact combination of compounds used in a particular coating will vary, depending on the degree of heat resistance the treated substrate requires. Like polyurethane coatings, high-temperature coatings can be classified according to the number of components in the system. One-component high-temperature coatings provide outstanding insulation and deliver performance benefits across a very broad spectrum of temperatures, while two-component high-temperature coatings are usually recommended if additional insulation is not needed.
