UV Cured Epoxide Coating

摘要

A new uv cured epoxide protective coating has been developed. This coating is based on a cycloaliphatic epoxide that can be cured in seconds with photoinitiators to a clear, durable surface. Modifiers can be added to improve flexibility, toughness, and adhesion. This coating is 100% solids; thus, compared to other solvent based coatings, it has the following advantages: low outgassing, low cure shrinkage, good aging characteristics, rapid processing, low toxicity, abrasion resistance, and excellent electrical and mechanical properties. The coating will bond to virtually any clean substrate. It has been successfully used on several projects and should continue to find wide-spread application. (ERA citation 11:020454)
