Hycar CTBN 1300X9 Carboxyl terminated butadiene-acrylonitrile copolymer Noveon Rubber - Elastomer >> Butadiene-acrylonitrile / Nitrile rubber, NBR ADHESIVE Hycar Reactive Liquid Polymers (RLP's) are 100% solids liquid rubbers used to improve the toughness, flexibility, adhesion or impact resistance of thermoset resin systems including epoxies, vinyl esters, unsaturated polyesters, acrylics and urethanes. The RLP polymers are a family of butadiene homopolymers and butadiene-acrylonitrile copolymers with functionality at the chain ends. Functional groups are carboxyl (COOH), amine (NH or NH2), methacrylate or epoxy. The acrylonitrile content varies in these polymers from zero to 26% which directly affect the solubility and glass transition temperatures (Tg's) of the materials. CTBNX 1300X9 is a carboxyl terminated butadiene-acrylonitrile copolymer containing pendent carboxyl functionality and is used predominately as a reactant with a base thermoset resin to gain product performance improvements. These resultant pre-reacts (adducts) can be incorporated at various levels to suit the needs of your specific formulation. Enhances the Toughness/Flexibility of Thermoset Resins Greater Functionality than Standard CTBN Polymers Increases Low Temperature Mechanical Properties Improves Durability (Fatigue Resistance) Improves Adhesion with Difficult to Bond Substrates Increases Impact/Crack Resistance Film and Paste Adhesives (Structural and Semi-Structural Applications)End uses include Aerospace, Automotive, Electrical/Electronics, and Industrial To ensure optimal product performance, store at room temperature or below. Butadiene-acrylonitrile copolymer. Used for film and paste adhesives (structural and semi-structural applications). Provides enhanced toughness/flexibility of thermoset resins. Increases low temperature mechanical properties and impact/crack resistance. Improves durability and adhesion with difficult to bond substrates.
