Erisys EMRA-1340 Adduct of a diglycidyl ether of bisphenol A and a butadiene-acrylonitrile elastomer CVC Epoxide (EP) >> Bisphenol A based ADHESIVE ERISYS ® EMRA-1340 Diglycidyl Ether of Bisphenol A Modified with a CTBN Elastomer ERISYS EMRA-1340 is a high viscosity adduct of the di-glycidyl ether of Bisphenol A (DGEBA) and a butadiene-acrylonitrile (CTBN) elastomer. The elastomer improves the toughness, and impact, thermal shock and peel resis-tance of the DGEBA resin. These improvements are at-tained with little loss of thermal resistance and modulus. EMRA-1340 is compatible with all standard epoxy resins and curing agents. EMRA-1340 is suggested for use as a toughener in fiber reinforced products, adhesives, molding compounds, potting and encapsulating com-pounds and chemical resistant coatings. Molding Compounds Adhesives Impact Resistance Coatings Thermocyclying Modifier for Epoxies Toughening of Prepregs and Composites High viscosity diglycidyl ether of bisphenol A modified with a butadiene-acrylonitrile elastomer. Used as a toughener in adhesives. Improves toughness, and impact, thermal shock and peel resistance. Reduces thermal resistance and modulus. Possesses compatibility with all standard epoxy resins and curing agents. Can be used as thermocyclying modifier for epoxies.
