Phenolic Novolac Epoxy Curing Agent in Low Viscosity for Moulding Compound

Product description

 

Phenolic Novolac resin is produced by condensing phenol with an insufficient amount of formaldehyde to complete the reaction in the presence of an acid catalyst. This produces a thermoplastic resin.

 

Phenolic Novolac resins are also 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.
