Anaerobically compositions containing acrylic ester-acids

摘要

Anaerobically hardening adhesive compositions principally composed of a polymerizable acrylic ester and an organic aerobically-inactive, anaerobically-active peroxide polymerization catalyst therefor possess improved latent adhesive properties for metals when they contain an acrylic ester-acid of the formula: wherein R is -H or -CH3; R' is H, halogen, -COOH, -CN, and loweralkyl, and X is a divalent C1-6 hydrocarbon group, or a mixture of such ester-acids.
