Vinyl ester resin composition, composite material containing the composition, and cured material of the composition or composite material

摘要

Problem to be solved: to provide a vinyl ester resin composition capable of maintaining a reduced amount of formaldehyde in a high temperature environment (e.g., 30 ° C.) without delay of curing time of the resin.In a vinyl ester resin composition comprising vinyl ester resin (a), formaldehyde capture agent (b), secondary amine compound (c) and ethylenic unsaturated monomer (d), the secondary amine compound is an acyclic aliphatic secondary amine.
