Epoxy Phenol Novolac Resins

Epoxy Phenol Novolac resins are polyepoxides obtained by reacting a phenolic novolac with epichlorohydrin. EPN resins contain more than 2 epoxy groups per molecule and can therefore be described as multifunctional epoxy resins. When cured, these EPN resins provide a high cross-link density due to the increased epoxy functionality. These EPN resins are recommended in formulations for high performance applications requiring excellent chemical resistance, solvent resistance and exceptional high temperature resistance than the standard Bisphenol A epoxy resins. These resins can be used in blends to upgrade the performance offered by bisphenol A and F epoxy resins. 

The Epotec series of Epoxy Phenol Novolac resins are available from low viscosity and high functionality as premier products for high corrosion resistance coatings and linings.

Typically, EPN resins are used in high temperature resistant Adhesives, corrosion resistant Marine Coatings, Maintenance Coatings, Industrial Coatings, Tank linings, Pipe Coatings, primers in Automotive, Coil & appliances, manufacturing of Epoxy Vinyl Esters etc.

Customized solvent-cut versions of EPN resins with Xylene, MIBK, MEK etc can also be made available upon request.
