Title:
ONE-PACK TYPE MOISTURE-CURABLE POLYURETHANE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/166610
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a one-pack type moisture-curable polyurethane composition which exhibits excellent adhesion to an object to be bonded (a coated plate). A one-pack type moisture-curable polyurethane composition according to the present invention contains a preliminary composition containing a urethane prepolymer (A) and an adhesiveness-imparting agent (B) that is a reaction product obtained by reacting a compound (b1) having three or more isocyanate groups and at least one compound (b2) selected from the group consisting of compounds represented by formulae (1)-(4) and hydrogenated products of compounds represented by formulae (1)-(3) so that the ratio of the isocyanate groups (NCO) in the compound (b1) to the hydroxyl groups (OH) in the compound (b2), namely NCO/OH is from 1.2 to 3.2. The content of the adhesiveness-imparting agent (B) is 0.1-10 parts by mass relative to 100 parts by mass of the preliminary composition.
