AI Technical Summary
Existing metal surface treatment compositions tend to cause film inhomogeneity and increased roller surface roughness when used on rollers, and do not have good recoatability, high temperature resistance, anti-darkening properties, corrosion resistance, alkali resistance, boiling water resistance, and solvent resistance.
Using an aqueous composition containing acrylic resin, film-forming aid, lubricant and water-soluble chromium compound, a uniform film is formed on the metal surface by methods such as roller coating, suitable for applications on stainless steel and polyurethane rollers.
It significantly extends the service life of the roller, forms a uniform film, and has excellent recoatability, high temperature resistance, anti-darkening properties, corrosion resistance, alkali resistance, boiling water resistance, and solvent resistance.
