Adhesive Containing High Solid Copolymer Polyol Polyurethane Prepolymer |
| 摘要 |
A high solid copolymer polyol adhesive composition comprising: (A) A polyurethane prepolymer comprising: (1) One or more polyisocyanates; (2) One or more compounds containing on average more than one isocyanate reactive compound; (3) A dispersion triol containing from 10 to 60 percent by weight, based on the weight of the dispersion, of particles of an organic polymer which is nonreactive with the isocyanate reactive compounds and the polyisocyanates having a particle size of less than 5 microns; wherein the prepolymer has a free isocyanate content of greater than 2.2 to 15 percent; and (B) A catalyst capable of catalyzing the reaction of isocyanate moieties with water. |
