Corro Therm Corrosion Resistant Coatings

Coating Specifications

CT-33 coating systems are inorganically bonded aluminum coatings developed specifically for high and cyclic temperature resistance and for certain corrosion applications in a salt environment. These coatings also feature excellent thermal stability and hardness along with good flexibility and superior adhesion. As service temperature increases, corrosion and oxidation protection also increase providing an optimum temperature range of 900°F to 1600°F for oxidizing environments. Thermal shock characteristics are outstanding, as the coating will remain totally adherent to most metals after repeated cycling between 1100°F and ambient temperature. When polished to a metallic luster, the surface becomes electrically conductive affording sacrificial and vastly improved corrosion protection.
