METHOD OF IMPROVING SURFACE SMOOTHNESS OF CURED PRODUCT AND CURED PRODUCT WITH IMPROVED SURFACE SMOOTHNESS

摘要

PROBLEM TO BE SOLVED: To improve the surface smoothness of a cured product of a curable composition comprising (A) an organic compound having at least two carbon-carbon double bonds having reactivity with an SiH group, (B) a compound having at least two SiH groups in the molecule, (C) a hydrosilylation catalyst, (D) an epoxy group-containing compound, and (E) silica having a silanol group as essential components. SOLUTION: The method of improving the surface smoothness of the cured product further incorporates an amine compound or an amine compound having at least one carbon-carbon double bond having reactivity with an SiH group into the above curing composition.
