Phenol polymer with formaldehyde glycidyl ether

Phenol polymer with formaldehyde glycidyl ether (CAS 28064-14-4), commercially recognized as polyglycidyl ether of phenolic novolac, is a multifunctional epoxy resin derived from novolac chemistry.

Where is Phenol polymer with formaldehyde glycidyl ether used?

• Protective coatings: high-performance tank linings, pipe coatings, and industrial floor systems
• Structural adhesives and composite matrices for automotive and aerospace components
• Electrical laminates and encapsulants: dimensional stability and dielectric performance
• Building and construction sealants and grouts: reactive binder where chemical resistance is a qualification requirement
• With three or more epoxide groups per molecule, it delivers higher cross-link density than standard diglycidyl ether resins.

Good to know: Buyers should confirm EEW, functionality, and softening point against their cure system and application specifications before procurement.

Commercial specifications

• Viscosity and epoxide equivalent weight (EEW) vary by grade
