Phenolic novolac epoxy resins are advanced thermoset polymers that offer exceptional resistance to high temperatures, chemicals, and abrasion. With its expertise in industrial paints and coatings, Blitzsch Kimya transforms this technology into high-performance products suitable for heavy-duty environments. This article provides a comprehensive overview of phenolic novolac epoxies, from their chemical structure to their application areas and Blitzsch’s innovative solutions in this field.
What is Phenolic Novolac Epoxy?
Phenolic novolac epoxy resins are multifunctional thermoset resins obtained by the reaction of phenol-formaldehyde novolac polymers with epichlorohydrin.
Since this structure contains more epoxy functionality than classical bisphenol-A epoxy resins, the crosslink density is higher.
Conclusion:
➡️ Higher heat resistance
➡️ Better chemical resistance
➡️ Lower dissolution and deformation rate
Highlights of Phenolic Novolac Epoxies
- Superior Thermal Stability: Maintains its mechanical strength up to 200–250 °C.
- High Chemical Resistance: Remains stable even in acid, solvent, fuel and alkaline environments.
- Wear Resistance: Provides excellent adhesion on metal surfaces and has high surface hardness.
- Crosslink Density: Hardness and rigidity increase thanks to the excess bonds between polymer chains.
- Long-Lasting Protection: Provides long-lasting protection even in harsh environments such as marine, petrochemical, energy and mining.
