Abstract
The present invention provides an anaerobic curing composition comprising a monofunctional or multifunctional acrylate or methacrylate as a polymerizable monomer having at least one functional vinyl group, 0.1 to 10 percent by weight of an organic peroxide and 0.1 to 10 percent by weight of at least one aromatic amine having a pKa of 6.5 to 9.0, based on the total weight of the monomer, which may be stored as a liquid for a long time and cures rapidly at anaerobic conditions, to form a strong bond between adjacent surfaces of, especially, metals, so that it is useful as an adhesive and sealant for metals.
Claims1
An anaerobic curing composition which comprises a monofunctional of polyfunctional acrylate or methacrylate monomer having at least one vinyl functional group, 0.1 to 10 percent by weight of an organic peroxide and 0.1 to 10 percent by weight of a lutidine having a pKa value in the range of 6.5 to 9.0, based on the total weight of the monomer, wherein the organic peroxide and the lutidine are employed in an amount of equivalent mole.
