DEN 426 - Description

D.E.N. 426 is an epoxidized phenolic resin of higher functionality than standard bisphenol A based liquid epoxy resins. Epoxy novolac resins combine, in one molecule, the thermal stability of a phenolic backbonewith the reactivity and versatility of an epoxy. They are distinguished by particular good thermal stability, mechanicalstrength and resistance against chemicals. They find ready acceptance for lining pipelines, storage tanks and pumps.

D.E.N. 426 was developed to fill the gap between the two functional standard bisphenol F based liquid epoxy resins and the high viscous epoxy novolac resins. The multi-functionality, ± 2.6 epoxy groups permole, of D.E.N. 426 produces a more tightly cross-linked cured system than bisphenol A based liquid epoxy resins leading to improved high temperature performance and improved resistance against various chemicals.

More information about DEN 426

  • Approximately 2.6 functional medium viscosity liquid epoxy novolac resin
  • Fills the gap between lower viscosity epoxy novolac resins such as D.E.N. 424 and higher viscosity epoxy novolac resins such as D.E.N. 431 and D.E.N. 438
  • When using D.E.N. 426 with carefully selected curing agents, the system provides faster thin film drying time at ambient temperature and has better resistance to chemicals such as acetic acid, toluene, and methanol
  • Can be formulated to fully cure at ambient temperatures with the correspondingcuring agents without the need of additional heat cure.
