550 °F to 1100 °F+ Coatings
High temperature coating systems for equipment exposed to sustained heat and corrosive operating conditions.
Protection for High Temperature Industrial Equipment
Industrial combustion and process equipment operating at elevated temperatures can also face thermal cycling, moisture, and corrosive byproducts that accelerate coating degradation.
For these demanding applications, Forrest recommends a high temperature primer and topcoat system designed to provide corrosion protection, adhesion, and durability for boilers, cyclones, exhaust systems, regenerative thermal oxidizers (RTOs), and other high-heat equipment.
This two-coat system combines 54H050 high temperature primer for corrosion protection and adhesion with 62H290 modified silicone topcoat for durable performance at sustained temperatures up to 1100 °F.
54H050 High Temperature Primer
A silicone epoxy co-polymer high-temperature primer designed to give excellent corrosion resistance in ambient or high temperature conditions up to 1100 ° F (593 °C).
