Abstract:
1. A method of bonding an adherend to a substrate which comprises applying a curable composition comprising at least one polymer or resin selected from the group consisting of (A) a reactive silyl group-containing polyoxyalkylene polymer, (B) a reactive silyl group-containing saturated hydrocarbon polymer, (C) a copolymer of which molecular chain is substantially made of one or more alkyl acrylate monomer unit(s) and/or alkyl methacrylate monomer unit(s), (D) an epoxy resin, (E) 120 to 250 parts by weight of a colloidal calcium carbonate having a particle diameter of not larger than 0.1 μm per 100 parts by weight of the (A) and/or (C) component and (F) 15 to 30 parts by weight of a thixotropic agent per 100 parts by weight of the (A) and/or (C) component, and having a viscosity before curing of not lower than 10,000 Pa·s as determined on a B8U type viscometer under the following condition; rotor No. 7; number of revolutions 0.5 rpm; in an atmosphere at 23°C., according to JIS K 7117 to the adherend and/or the substrate and then joining the adherend and the substrate together without temporary tacking wherein the adherend is a building material panel selected from the group consisting of decorative plastic boards and gypsum boards, and the substrate is mortar.
