Method of bonding adherend

A curable composition which comprises at least one polymer or resin selected from the group consisting of

• (A) a reactive silyl group-containing polyoxyalkylene polymer,
• (B) 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)
• which has 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;
• in number of revolutions 0.5 rpm;
• in an atmosphere at 23° C., according to JIS K 7117
• (C) 100 to 500 parts by weight of a filler per 100 parts by weight of (A) and/or (C) components and
• (D) 5 to 30 parts by weight of a thixotropic agent parts by weight of (A) and/or (C) components.

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) and
• (D) an epoxy resin,
• (E) 100 to 300 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 (A) and/or (C) components and
• (F) 5 to 30 parts by weight of a thixotropic agent parts by weight of (A) and/or (C) components, 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.
