Abstract

The epoxy polymer based on Ethal-247 resin and cycloaliphatic Ethal-45M curing agent was exposed to Gelendzhik and Saransk atmosphere. The color characteristics of the specimens were measured and it was shown that colorimetric property such as a color difference of the polymer surface is sensitive to initial stages of weathering. It was shown that the natural UV-radiation is a dominant factor for polymer degradation. The application of solar radiation doze provides more reliable results.
