AI Technical Summary

Technical Problem

Existing automotive clear coats have poor water resistance and durability, resulting in a mismatch between the performance of the repaired paint and the original high-temperature paint, which affects the vehicle's value.

Method used

The varnish component, which combines carboxylated polycarbonate and epoxy-based polyacrylate resin, forms a cross-linked structure through the reaction of carboxyl and epoxy groups, thereby improving the adhesion, chemical resistance, water resistance, and weather resistance of the paint film.

Benefits of technology

It improves the overall performance of the clear coat, including adhesion, lightfastness, weather resistance, and chemical resistance, ensuring that the repaired paint performs the same as the original paint and avoiding excessive repairs that could devalue the vehicle.
