Document Type and Number:
Japanese Patent JPS5654348
Kind Code:
B2
Abstract:
Storage-stable anaerobic curing adhesive compositions useful as anaerobic adhesives and sealants are prepared by first mixing a polymerizable acrylate ester monomer, an inhibitor for free radical polymerization, a chelator, and at least an effective amount of an accelerator system consisting of an organic cyclic sulfimide, preferably saccharin, and an aromatic tertiary amine. The resultant homogeneous mixture is thereafter heated at a temperature of about 45 DEG -100 DEG C. for a period of time sufficient to provide the composition with anaerobic curing properties and a specified minimum amount of active oxygen. In one embodiment, the mixture is stirred at a temperature of 45 DEG -70 DEG C. for 10-24 hours. In another embodiment, the mixture is maintained at an elevated temperature without stirring.
