High-Temperature Coatings
High Temperature Coatings are applied to insulation and refractory surfaces to add a durable, protective layer in demanding environments. Many insulation materials perform well thermally but can be vulnerable to mechanical wear, airstream erosion, or chemical exposure—coatings help create a tougher surface “crust” that protects the system and supports longer service life. Coatings can also be used to protect steel surfaces in hot-gas environments and to help manage heat where the application calls for it.
Types of Coatings
Protective Surface Coatings
Designed to protect insulation from abrasion, incidental impact, chemical attack and general mechanical abuse by creating a hardened outer layer.
Airstream / Erosion-Resistant Coatings
Used where hot gases, particulates, or high-velocity airflow can erode exposed insulation or refractory surfaces—adds protection in ducts, stacks, and flow paths.
Chemical-Resistant Coatings
Applied when atmospheres or process contaminants can degrade exposed materials; adds another line of defense against chemical attack.
High-Temperature Insulation Coatings
Selected for hot-face conditions where a thin, applied layer helps protect the underlying insulation system and supports thermal-performance goals as part of a broader refractory lining design.
Installation
Installation
Most coatings are applied by spray (air gun) for consistent coverage, and many can also be rolled or brushed on depending on the product and access. Coating selection and thickness are typically based on exposure conditions (mechanical wear, airstream velocity, chemistry), the insulation/refractory substrate as well as the type of coating it is.
