HYPRO® 1300X18 CTBNX

HYPRO® 1300X18 CTBNX by Huntsman is a carboxyl terminated butadiene-acrylonitrile copolymer containing pendent carboxyl functionality. It has greater functionality than standard CTBN polymers. This reactive polymer is a 100% solid liquid rubber which is used to improve the adhesion, toughness, flexibility and impact resistance of thermoset resin system including epoxies, vinyl esters, unsaturated polyesters, acrylics as well as urethanes. HYPRO® 1300X18 CTBNX increases low temperature mechanical properties and improves durability (fatigue resistance). It is also used predominantly as a reactant with a base thermoset resin to gain product performance improvement. This resultant pre-react (adduct) can be incorporated at various levels to suit the needs of specific formulation. It is used in film and paste adhesives that is further used in structural as well as semi-structural applications.
