Document Type and Number:
Japanese Patent JP2000515173
Kind Code:
A
Abstract:
The invention is a one-part adhesive composition comprising: A) i) an isocyanate functional polyurethane prepolymer having a free isocyanate content of from 0.8 to 2.2 percent and particles comprising a curing agent for an isocyanate functional polyurethane prepolymer encapsulated within a coating material; or ii) a prepolymer comprising the reaction product of one or more polyisocyanates; one or more compounds containing on average more than one isocyanate reactive compound; and a dispersion triol containing from about 10 to about 60 percent by weight based on the dispersion of particles of an organic polymer which is nonreactive with the isocyanate reactive compounds and the polyisocyanates having a particle size of from about 5 to about 50 microns; wherein the prepolymer has a free isocyanate content of from about 0.8 to about 2.2 percent; and B) a catalyst capable of catalyzing the reaction of isocyanate moieties with isocyanate reactive moieties. In yet another embodiment, the invention is a process for binding two substrates together which comprises contacting an adhesive composition of the invention with at least one of the substrates and contacting the substrates together along the portion of the substrate(s) to which the adhesive has been applied before the adhesive applied cures and allowing the adhesive to cure and bond the substrates together.
