A process for fixing an article to a substrate with a mounting set including two receptacles storing an aerobic adhesive and a hydrophilic substance, respectively. The aerobic adhesive and the hydrophilic substance are removed from the two receptacles and then mixed together to prepare the fastening. A layer of the fastening composition is applied to the article. The article is fixed to the substrate by pressing the layer of the fastening composition against the substrate. The aerobic adhesive in the layer hardens because of the moisture contained in the hydrophilic substance.

A curable composition includes an organic polymer containing a reactive silicon group (A), and a bound substance of kaolinite and quartz (B) at a proportion of 30-200 parts by weight relative to 100 parts by weight of the organic polymer containing a reactive silicon group (A).

The present invention provides a curable composition useful as a contact adhesive which has a high rate of initial tack development, high tack strength, and long retention time of the developed tack. The curable composition includes an organic polymer (Q) containing a reactive silyl group, and a linear organic polymer (P) having a number average molecular weight larger than that of the polymer (Q) and having a reactive silyl group containing three hydrolyzable groups at only one terminal. The organic polymer (P) and the organic polymer (Q) are mixed at a mixing ratio (P):(Q), in terms of parts by weight, of 60:40 to 5:95.
