Heat-resistant paints are used for corrosion protection of high-temperature equipment surfaces; common locations include chimneys, exhaust ducts, boilers, heat exchangers, steam piping, cracking furnaces and metallurgical equipment. Conventional epoxy or polyurethane begins to degrade at 120–150°C, so a silicone resin system is required—the bond energy of the siloxane bond is far higher than that of the carbon-carbon bond, allowing continuous service at 200–600°C (depending on the specific model). By temperature rating: the low-temperature range (200–300°C) is mostly modified silicone, balancing adhesion and corrosion resistance; the medium-temperature range (300–500°C) uses pure silicone systems; higher temperatures require aluminium-powder heat-resistant paint (aluminium powder forms a dense oxide film at high temperature) or ceramic coatings. Selection considerations: actual service temperature, whether thermal cycling occurs, and the trade-off between ambient-temperature corrosion resistance and heat resistance—products with higher heat resistance generally have weaker ambient-temperature corrosion resistance. For application, many products requireheat curing(stepwise heating to above 200°C); where on-site heating is not possible, room-temperature-curing types shall be selected. This page summarises original manufacturer data for heat-resistant paints from various brands.

This page compiles original-factory technical data sheets by tag. The same model may appear under several tags at once (for example, a water-borne epoxy primer belongs to "water-borne", "epoxy" and "primer"), the more entry points a model has, the more easily it is found by search habits.
