PROBLEM TO BE SOLVED: To provide an adhesive composition which satisfies all of high thermal conductivity, high tensile adhesion strength, high handleability and working efficiency, and high safety, and is suitable for adhesive application of a floor heating panel.SOLUTION: A moisture-curable adhesive composition contains: 100 parts mass of a polyoxyalkylene polymer having 1.5 or more crosslinkable silyl groups in one molecule thereof and 4,000-30,000 number-average molecular weight (Mn); and 400-700 parts mass of a thermally conductive filler. It is preferable that the number of the crosslinkable silyl groups contained in one molecule is 1.5-5 and the crosslinkable silyl group is shown by general formula (1) (wherein R is a 1-20C substituted or unsubstituted univalent organic group and Rs can be the same or different from one another when a plurality of Rs exist; X is a hydroxyl group or a hydrolyzable group or Xs can be the same or different from one another when a plurality of Xs exist; n is an integer of 1-3).

Abstract:
PROBLEM TO BE SOLVED: To provide an adhesion method in which delicate position adjustment of an adherend, such as an interior panel, adhered once is made possible while securing adhesion strength required for temporary fixing with only an adhesive without using a double-sided adhesive tape and thereafter, adhesion strength of permanently fixing the adherend can be imparted. SOLUTION: The adhesive comprising an adhesive A containing a first polymer having an alkyldialkoxysilyl group at the molecular end and an adhesive B containing a second polymer having a trialkoxysilyl group at the molecular end is used, and the curing speed, obtained when the adhesive A and the adhesive B are mixed, is larger than the curing speed obtained when the adhesive A or the adhesive B is cured in a single form. An unmixed area, where at least one of the adhesive A and the adhesive B is applied, is formed on the adherend surface of at least one adherend, and a mixed area, where the adhesive A and the adhesive B are mixed, is formed immediately before bonding adherends to each other or by bonding the adherends to each other, and then the adherends are bonded to each other.

Abstract:
PROBLEM TO BE SOLVED: To provide a reactive hot melt resin composition that exhibits the same heat resistance as one comprising a boron halide and/or a boron halide complex and substantially contains neither halogen compounds nor organic tin compounds. SOLUTION: The reactive hot melt resin composition comprises a curable resin (A) bearing a hydrolyzable silicon group in the molecule and a carboxylic acid metal salt (B). The carboxylic acid metal salt (B) is preferably contained in an amount of 0.01-10 pts.mass based on 100 pts.mass of the curable resin (A). The carboxylic acid metal salt (B) is preferably at least one compound selected from carboxylates of calcium, vanadium, iron, titanium, zirconium, cerium, aluminum, potassium, bismuth, barium and zinc.
