摘要:
A curable impregnation sealant composition comprising a curable monomer, e.g., a (meth)acrylic acid ester monomer, of a type adapted for curing by heat and/or substantial absence of oxygen, and a curable monomer-soluble reactive bismaleimide of a type and in a solubilized amount providing enhanced high temperature resistance in the impregnation sealant composition when cured.
