EPOXY RESIN NPPN-638S

CAS # 28064-14-4

General:
NPPN-638S has two advantageous properties, heat resistively of phenolic backbone and reactivity of an epoxy. Comparing with BPA-based epoxides which have two epoxides per molecule,NPPN-638S has an average of 3.6 epoxy groups per molecule.
NPPN-638S provides tightly cross-linked cured systems having better elevated temperature performance, chemical resistance and adhesion than the BPA-based resins.

Chemical Composition: Phenolic novolac epoxy resin.

Application:
1. Laminates.
2. Civil engineering.
3. Filament winding.
4. Composite


Storage properties:
At least 12 months in sealed containers at ambient temperature.
