High temperature coatings as the name suggests, are those that can help prevent the rapid corrosion and degradation of materials and equipment that can occur at high operating temperatures. These coatings are designed to withstand high temperatures for long periods of time.
Industrial high temp coatings are widely used in process based facilities such as refineries, petrochemical plants, pulp and paper mills and power plants. These facilities usually contain extensive networks of pipe that need to be diligently protected from corrosion under insulation and away from the naked eye. Therefore, it is essential that users have confidence in the effectiveness of their high temperature coatings. Aerospace propulsion systems such as incinerators, gas turbines, industrial furnaces, and industrial silencers and industrial processes which include high temperature equipment, stacks, mufflers, boilers, jet engines, heat exchanges, chemical processing equipment, and outdoor electrical equipment are the other areas high temperature coatings are necessary.
High temp coatings are also often used on smokestacks, kiln exteriors, portable fireplace units and so on. Uses determine the different properties required of a high temperature coating. Customers will ask if a high temp coating will provide the corrosion protection they're looking for. Or, simply, if it is safe to use on a barbeque pit.
When selecting a high temperature coating, ease of application should be a major consideration. It can often be the deciding factor when choosing between two products. The main reason being, high temp coatings are often not applied as a part of some major recoating initiative, but rather as and when required, with touch-ups being done at select portions at a facility.
