▎ 摘　　要

NOVELTY - Two-part curable composition which cures to form a thermally conductive cured product, comprises a first part comprising (1) at least one metal catalytic component for catalyzing the cure reaction, (2) a non-reactive diluent component, (3) a wetting agent component, (4) a filler component, (5) a rheology modifier component, and (6) a pigment component; and a second part comprising (1) at least one silane terminated polyurethane polymer, (2) a moisture scavenger, (3) a non-reactive 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 two-part curable composition is used for forming a thermally conductive cured product (claimed). 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 two-part curable composition has enhanced thermal conductivity and minimized environmental impact.
