Title:
ANEAROBIC ADHESIVE COMPOSITION CONSISTING OF POLYFUNCTIONAL ACRYLATE NNVINYL AMIDE
Document Type and Number:
Japanese Patent JPS5385833
Kind Code:
A
Abstract:
A solventless, fast-setting anaerobic adhesive composition comprises two monomer parts which are adapted to be copolymerized anaerobically at ambient temperature between opposing surfaces to form a high-strength bond thereto. One part comprises a multifunctional acrylate monomer and the other an N-vinylamide monomer. The formulation also includes a redox system consisting of oxidizing and reducing agent components for initiating polymerization between said monomers. The oxidizing agent of the redox system may be present in either one of said parts, preferably with the multifunctional acrylate. The reducing agent is present in the other part, usually the N-vinylamide. Upon anaerobic admixing of the respective parts of the composition at ambient temperature, the oxidizing and reducing agents react to generate free radicals which initiates copolymerization of the monomers to form the desired high-strength adhesive bond to said surfaces.
