Surface Treatment Chemicals
Surface treatment chemicals are essential for enhancing the durability and corrosion resistance of materials in various industries. They help in removing oil stains, applying protective layers, and preventing damage to metal surfaces like steel parts through processes such as oxidation, phosphating, and plating.
These chemicals also play a key role in the surface treatment process, utilizing chemical and electrochemical methods for applications like cathodic protection and chemical surface heat treatments. By improving material performance and longevity, surface treatment chemicals ensure protection against corrosive chemicals, extending the life of industrial components.
Degreasing
Degreasing is a key step in removing oil stains from metal surfaces before the surface treatment process. It improves corrosion resistance by preparing the surface for better adhesion. Our solution uses alkaline cleaners with surfactants to boost cleaning. The process has two stages: knock-off degreasing and thorough cleaning, which are applied through spray or dip methods. Afterward, water rinsing ensures all contaminants are removed, preparing steel parts and surfaces in various industries for the next treatment stage.
