AI Technical Summary
Technical Problem
The poor mechanical properties of existing color-coated steel sheets result in poor paint adhesion, making them prone to paint peeling and affecting durability.
Method used
A chemical layer is applied to the surface of the primer and cross-links with the primer layer to form a dense conversion film. Combined with components such as composite clay, treated glass fiber and fumed silica, a multi-layer coating structure is formed to enhance adhesion and mechanical properties.
Benefits of technology
It improves the mechanical strength, flexibility and corrosion resistance of the coating, prevents paint peeling and cracking, ensures uniform color and gloss of the topcoat, and extends service life.
