On October 25-28, the 24th National Academic Exchange Conference on Epoxy Resin Application Technology and the Member Representative Conference of the Epoxy Resin Branch of the China Synthetic Resin Association were held in Mianyang, Sichuan. More than 200 experts and scholars from universities, government agencies, enterprises, and other parts of the country in the field of epoxy resin gathered together to discuss the current development status and prospects of epoxy resin application technology.
At the invitation of the conference, our company's Director of Applied Research and Development, Zhou Xin, attended the conference and delivered a report titled "Application of Alicyclic Epoxy Resins in Weatherproof Materials". He shared the innovative performance characteristics and applications of alicyclic epoxy resins with the attending government, enterprises, experts and scholars.

Cycloaliphatic epoxy resin - medium and low temperature curing system
Cycloaliphatic epoxy resin medium and low temperature curing system can achieve room temperature or medium and low temperature curing. With a high fault tolerance rate, (A:B=100:60-90), the curing process is more stable and is not easily affected by moisture, alkalinity and other substances. The cured product has very good UV resistance:
1. The cured product is colorless and transparent with high light transmittance;
2. The cured product has high hardness, Shore hardness 85D;
3. The cured product has excellent resistance to yellowing.
Cycloaliphatic Epoxy Resin - Composite Applications Photovoltaic Module Frame
With the current high price of aluminum and increasing pressure on frame costs, component companies have increased demand for cost reduction; specific scenarios such as offshore, coastal photovoltaic, and photovoltaic projects for saline-alkali land also put forward higher requirements for corrosion resistance and weather resistance.
Cycloaliphatic epoxy resin can be used in composite material fields such as UV cure prepregs, rapid winding resins, UV cure repair resins and photovoltaic module frames. It can be used in offshore and water floating photovoltaic power stations, saline-alkali photovoltaic power stations, distributed rooftop photovoltaic power stations, etc.
Cycloaliphatic epoxy resin has excellent aging resistance and retains excellent mechanical properties after aging.
After acid, alkali, double 85, and UV aging tests, the mechanical retention rate is >90%, and it can be applied to outdoor weather-resistant composite materials.
In the future, Donghua Materials Science will continue to carry out the research and development of special epoxy resin and curing agent modification, system materials, and the development of corresponding application processes to provide customers with higher quality products and services and to drive the industry towards a more sustainable future!
