The role of allyl glycidyl ether in epoxy resin modification

Hits: 197 img



1. Improve the flexibility of epoxy resin

By introducing AGE into the epoxy system, the crosslinking density can be reduced, so that the resin can maintain strength while increasing flexibility, thereby reducing brittle cracking. Especially in applications such as structural adhesives and electronic packaging materials, the modified epoxy resin can improve impact resistance and extend service life.

2 Enhance adhesion and chemical resistance
The active groups of AGE can react with hydroxyl groups or other functional groups on the surface of the substrate to improve the bonding properties of epoxy resin. In addition, the allyl group in its structure helps to improve the solvent resistance of the resin, so that it can still maintain good adhesion and durability in harsh environments.

3 Improve heat resistance and weather resistance
AGE-modified epoxy resin exhibits better high temperature resistance and can maintain stable physical and mechanical properties at higher temperatures. In addition, it can reduce UV degradation and improve weather resistance, making it more durable in outdoor applications (such as anti-corrosion coatings).
