Production manner null of adhesion agent composition and moisture permeation waterproofing cloth for non porosity film die moisture permeation waterproofing

摘要

PPROBLEM TO BE SOLVED: To provide an adhesive composition for nonporous film type moisture-permeation and waterproofing excellent in touch feeling, water resistance, moisture permeability, washing resistance, etc. and to provide a method for producing a nonporous film type moisture-permeable and waterproof fabric by using the adhesive composition. PSOLUTION: The adhesive composition for nonporous film type moisture-permeation and waterproofing is obtained by reacting (A) an organic polyisocyanate component with (B) a first polyol component containing a polyoxyethylene group composed of four or more oxyethylene units and containing at least two active hydrogens which are reactive with an NCO group and (C) a second polyol component having at least two active hydrogens which are reactive with an NCO group so that the ratio (molar ratio) of NCO/OH becomes 0.65-0.99 to provide (P) a water dispersion of a polyurethane prepolymer having terminal hydroxy groups and formulating the component (P) with (D) a water-dispersing type polyisocyanate-based crosslinking agent.
