This invention provides a method which is capable of strong and rapid-curing adhesion of various kinds of components including plastic components. Especially, this method can be industrially utilized with high efficiency in in-line adhesion assembly of various kinds of components, for example, plastic components, such as adhesion assembly of optical disks by adhering plastic plates together. Namely, this method comprises the steps of forming a face for effecting curing acceleration for an anaerobic curing adhesive on one or both of the adhering surfaces of the components to be adhered, coating the anaerobic curing adhesive on one or both of the adhering surfaces of the components, and laying one adhering surface on the other adhering surface of the components.

Rapid curing adhesion method

A two-part room temperature curable composition comprising liquid part A containing an organic polymer having reactive silicon groups, and a promoter for the polymerization of a radically-polymerizable monomer as essential components; and liquid part B containing the radically-polymerizable monomer, an initiator for the polymerization of the radically-polymerizable monomer, and an accelerator for the curing of the organic polymer having reactive silicon groups as essential components. The two-part composition can be mixed together at room temperature and has the property of curing rapidly to produce a product with a flexibility equivalent to rubber materials. Thus, when used as a flexible protective coating, potting material, sealing agent or adhesive, this product can reduce working time while guaranteeing high reliability and can prevent pollution of the working environment.
