HyPox RF1341 Epoxy phenol novolac resin modified with CTBN elastomer CVC Epoxy Resins >> Phenol & Cresol (Novolacs) Coatings >> Solvent-Free/ High-Solids HyPox RF1341 is a Bisphenol F epoxy resin modified with a butadiene acrylonitrile elastomer. The CTBN elastomer is adducted to the epoxy resin. The adduct has epoxy functionality and provides improved toughness and impact resistance. Unlike Bisphenol A modified elastomers, HyPox RF1341exhibits superior chemical resistance, particularly to 98% sulfuric acid, MEK, toluene, alcohols and other aggressive solvents. HyPox RF1341 is suggested for use in 100% solids civil engineering and chemical resistant coatings applications. Blends of HyPox RF1341 with most standard epoxy resins are possible. Cures can be accomplished with all standard curing agents suitable for epoxy resins. Cure speed is comparable to standard liquid Bisphenol F epoxy resin. It is used in crack bridging in secondary containment coatings, impact resistance coatings, thermocycling modifier for high chemical resistance coatings, toughener for epoxy novolacs, toughening of prepregs and composites, adhesives. Bisphenol F epoxy resin modified with a butadiene acrylonitrile elastomer. Used in crack bridging in secondary containment coatings, impact resistance coatings, thermocycling modifier for high chemical resistance coatings and as toughener for epoxy novolacs. Provides improved toughness and impact resistance.
