Nanya Epoxy Resin NPPN-638S for Adhesives & Sealants & Paint & Epoxy Floor Coating
NPPN-638S is a novolac epoxy resin with a heat-resistant backbone of benzene rings and a multifunctional epoxy group with high bridge density.
Due to the structural characteristics, it has a wide range of processing conditions.
NPPN-638S can be hardened with polyurethane, phenolic, polyester resin or different anhydrides to produce high-performance circuit boards
Substrate (prepreg) or composite material, the substrate produced has high Tg value, good heat resistance and chemical resistance.

Application:
Used to make anti-corrosion coatings, powder coatings, inks, adhesives, insulating materials, etc.
Advantage:
1. Strong adhesion and high mechanical strength.
2. Because no small molecules are formed during curing, the density is high, and the shrinkage rate during curing is low, about 2%.
3. Good corrosion resistance.
4. Good heat resistance.
5. Good electrical insulation.
6. Good water resistance. The water absorption rate at room temperature is less than 0.5%. After one month of high temperature, the strength is reduced by less than 10%. It can be used as a waterproof and moisture-proof material.
7. Easy to cure and form.
Package: 220kg/barrel, 80barrels/20DC with pallets,
Storage: Cool and dry place.
