▎ 摘  要

NOVELTY - Two-part curable composition which cures to form a thermally conductive cured product, comprises a first-part comprising (1) a maleic anhydride adducted polybutadiene component, (2) a non-reactive diluent component, (3) a wetting agent component, and (4) a filler component, and a second-part comprising (1) a hydroxyl terminated polybutadiene component, (2) a catalytic component for catalyzing the cure reaction, (3) a diluent component, (4) a filler component, and (5) a wetting agent component, where at least one of the filler components of the first-part and the second-part comprises a thermally conductive filler. USE - The composition is used for bonding heat generating components, such as automotive electrical battery pack components, high-capacity batteries and electric motors in electric and hybrid vehicles. ADVANTAGE - The composition enhances the thermal conductivity, minimizes environmental impact of these products, forms cured product which has excellent elasticity and elongation properties, excellent thermal and electrical properties, and has excellent water proofing properties, high resistance to occurrence of cracks and chemical resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a thermally conductive cured product formed using the two-part curable composition.
