Epoxy resins are widely used in coatings thanks to their excellent adhesion to materials and their durability. However, epoxy resins typically contain aromatic groups with strong absorption in the UV range. This makes epoxy structures vulnerable to UV degradation. The performance of one company’s stabilizers in a typical commercial epoxy resin with hardeners are tested and reviewed in this article.
Formulations are sometimes adjusted by fine-tuning various additives, including antioxidants and light stabilizers, which provide different thermal and light stabilization properties. It is very important to find the best combination of additives to achieve the necessary performance, especially if the final substrate or area to be powder coated requires specific durability or heat resistance.
