NPPN-638
Epoxy resin

NPPN-638 has two advantageous characteristics, namely the heat resistance and epoxy reaction performance of phenol. Compared with the basic epoxy resin term of BPA with an average molecular weight of 2 epoxies, the average molecular weight of NPPN-638 is 3.6. A sturdy cross bonding curing system has better high-temperature properties, chemical resistance, and adhesion than BPA basic resins.
