AI Technical Summary

Technical Problem

Epoxy compositions used in protective and decorative coatings for steel structures in harsh environments lack sufficient UV resistance, weather resistance, and often result in brittle bonds that spread corrosion, while maintaining mechanical properties and processability is challenging.

Method used

A two-component composition comprising a silicone-based resin with epoxy functional groups and a curing agent containing alkoxy-containing amino-functional silicone resin, which reacts without a catalyst, achieving a balanced cure at room temperature, providing flexibility, weather resistance, and high UV resistance.

Benefits of technology

The composition exhibits excellent flexibility, corrosion resistance, gloss retention, and UV resistance, with a long open time, ensuring effective coating application on large areas without brittleness or rapid curing issues.

Abstract

The present invention relates to a two-component (2K) composition comprising, as a first component, a silicone-based resin containing an epoxy functional group, optionally an epoxy resin and a silicone acrylate oligomer, and, as a second component, a curing agent containing at least one alkoxy-containing amino-functional silicone resin and an aminoalkoxysilane. By reacting the two components of the composition, a cured product that exhibits processability while maintaining mechanical properties when cured can be obtained.
