CAS NO:25068-38-6 Poly(Bisphenol A-co-epichlorohydrin)/Araldite 506 Epoxy Resin

The core characteristics are: when the molecular weight is low, it is a viscous liquid, has strong hydrophobicity, high epoxy group reaction activity. It belongs to a thermosetting resin. It can only possess practical properties such as high mechanical strength, heat resistance, chemical resistance, and electrical insulation after being cross-linked and cured with a curing agent.

1. Precise ratio of curing agent
2. Uniform stirring
3. Defoaming
4. Pre-treatment of substrate
5. Appropriate addition of additives

Excellent comprehensive performance, good processability, wide compatibility with substrates, low cost, and large modification space. It is a key basic chemical raw material for coatings, adhesives, composite materials, and the electronics industry.

The collaborative essence of the three elements lies in the epoxy cross-linking to form a network as the carrier. The rigidity of the aromatic rings and the flexibility of the ether bonds complement each other and balance each other, ultimately constructing a dense, stable, and flexible-integrated three-dimensional network, endowing the cured resin with excellent comprehensive performance in all directions. This is also the structural basis for this bisphenol A epoxy resin to become a universal core resin.

Low viscosity characteristics are the core of FRP manufacturing process. These characteristics enable efficient impregnation, excellent wettability, and compatibility with multiple processes, ensuring uniform composite of resin and glass fibers and strong interface bonding, thereby eliminating forming defects at their source and enhancing production efficiency and product appearance.
