Low Viscosity Novolac Phenolic Resin Pellet as Epoxy Hardener for Copper-clad Laminates

Product description

The Novolac Phenolic resin Pellets are synthetic polymers formed as condensation products of phenols and formaldehyde under acidic catalyst and a molar excess of phenol to formaldehyde in high purity.

Application

The Novolac Phenolic resins are recommended used as curing agents or hardeners for epoxy resins in applications such as molding materials, laminates, coatings and adhesives. The phenolic novolac resins used are non-heat reactive materials by themselves, but have phenolic-OH groups that react with epoxy groups. Since the curing mechanism does not produce by-products, thick sections may be obtained without voids and stresses and with low shrinkage
