Full Description

Cresol novolac epoxy resin (CAS 37382-79-9), a multifunctional epoxy resin built on an o-cresol-formaldehyde novolac backbone. The high epoxy functionality produces heat- and chemical-resistant cured networks used in protective coatings, adhesives, and electrical laminates.

Frequently Asked Questions

What is the difference between standard epoxy resin and novolac epoxy resin?

Standard bisphenol-A epoxies are difunctional (two epoxide groups per molecule), while cresol novolac epoxy resin (CNE, CAS 37382-79-9) is multifunctional, built on an o-cresol-formaldehyde novolac backbone with several epoxide groups per chain. The higher functionality yields a more densely crosslinked cured network with greater heat and chemical resistance. This makes CNE the preferred choice for high-temperature coatings, electrical laminates, and adhesives.

What is cresol novolac?

Cresol novolac is the o-cresol-formaldehyde condensation polymer that forms the backbone of cresol novolac epoxy resin. Reacting this novolac with epichlorohydrin introduces multiple epoxide groups, producing the multifunctional CNE resin (CAS 37382-79-9). RawSource supplies CNE under HS code 3907.30 (epoxide resins).

What is novolac epoxy used for?

Cresol novolac epoxy resin is used in heat- and chemical-resistant protective coatings, electrical laminates, and high-temperature adhesive formulations. Its high epoxy functionality produces cured networks that hold up under elevated service temperatures and aggressive chemical exposure.

How is bulk cresol novolac epoxy resin packaged and ordered?

RawSource distributes CNE in industrial quantities to manufacturers. Packaging, viscosity grade, and lot volume are confirmed per order; request a bulk quote with your target spec and quantity. A Certificate of Analysis (CoA) and Safety Data Sheet (SDS) are provided with each shipment.

What is the cost of bulk cresol novolac epoxy resin?

Bulk CNE pricing depends on grade, packaging, order volume, and ship-to location, so it is quoted per order rather than listed. Submit a bulk RFQ with your required quantity and specification and RawSource will return current pricing.
