ONE-COMPONENT MOISTURE-CURABLE POLYURETHANE ADHESIVE AND METHOD FOR BONDING FLOORING MATERIAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a one-component moisture-curable polyurethane adhesive which quickly reacts with moisture after the application to cure in a short time, forming a tough rubberlike elastomer, and can strongly bond various resin-made flooring materials, such as tiles or sheets, and waterproof materials, especially a flexible polyvinyl chloride sheet, to various substrates; and a method for bonding flooring materials using the same.;SOLUTION: This one-component moisture-curable polyurethane adhesive contains an isocyanate-group-containing urethane prepolymer and a modified isocyanate compound other than the prepolymer. A resin-made flooring material is bonded to a substrate by using this one-component moisture-curable polyurethane adhesive.;COPYRIGHT: (C)2003,JPO
