Recent development of weather-resistant epoxy coatings for outdoor application
The aging mechanism of epoxy resin coatings was introduced.From the perspective of the structure-activity rela-tionship between the structure of epoxy resin and the properties of modified resin,the research progresses of epoxy resin coatings with high weather resistance prepared by modifying epoxy resin with aliphatic epoxy resin,silicone resin,acrylate and nanoparticles at home and abroad in recent years were reviewed.The problems faced in this field were analyzed and the future development direction was pointed out.
