An anaerobic adhesive composition having enhanced toughness and resistance to crack propagation, particularly subsequent to thermal exposure, comprising a combination of three monomers consisting of (a) at least one (meth) acrylate monomer, (b) at least one (meth)acrylate-terminated urethane modified acrylonitrile/butadiene prepolymer, and (c) at least one (meth)acrylate-terminated acrylic/polyisocyanate adduct.

Anaerobic compositions with enhanced toughness and crack resistance

The present invention provides anaerobic adhesive compositions, reaction products of which demonstrate controlled-strength at ambient temperature conditions and enhanced resistance to thermal degradation at elevated temperature conditions. The compositions are (meth)acrylate- and/or polyorganosiloxane-based and may include one or more of a variety of other components, such as certain coreactants, a maleimide component, a diluent component reactive at elevated temperature conditions, mono- or poly-hydroxyalkane components, and other components.

High temperature, controlled strength anaerobic compositions curable under ambient environmental conditions
