High humidity, high temperature or high acid concentration environment is always be a difficult problem for anticorrosion coatings, some material improved its anticorrosion property, but it becomes more fragile which can not meet the requirements of huge steel structure or concrete surface. SWD ceramic coating combines inorganic SiO2 which has strong anticorrosion and temperature variation resistance with organic compound. It is two components polyfunctionality, solvent free coating, the cured film has high crosslinking density, there is no hydroxyl and ester in the molecular chain structure but strong chemical bond ester bond (C-O-C). So the anticorrosion performance is excellent.
Characteristics
Ceramic coating can resist any high acid, alkali and other solvents, the coating film is compact and strong that can withstand the cyclic stress damage of steel structure and small cracks of concrete surface, with excellent adhesive strength on various metal or non metallic materials, high heat resistant and temperature shock resistance. Impact and collision resistance and abrasion resistance. Anti-UV and weather that can be long-term applied outdoor. Ceramic coating is solvent free, eco friendly, high hardness and good flexibility, it will not peel off or crack after long term use. Several types available for different corrosion environment conditions.
