摘要： The instant invention is a sealant composition comprising an ultra-high solid polyurethane dispersion comprising. The ultra-high solid polyurethane dispersion comprises (1) a first component comprising a first polyurethane prepolymer or a first polyurethane prepolymer emulsion, (2) a second component comprising a media phase selected from the group consisting of a second polyurethane prepolymer emulsion, a low solid content polyurethane dispersion, a seed latex, and combinations thereof; and (3) a chain extender. The ultra-high solid polyurethane dispersion has at least a solid content of at least 65 percent by weight of solid content, based on the total weight of the ultra-high solid polyurethane dispersion, and a viscosity of less than 5000 cps at 20 rpm at 21° C using spindle #4 with Brookfield viscometer. The sealant composition may further include optionally one or more surfactants, optionally one or more dispersants, optionally one or more thickeners, optionally one or more pigments, optionally one or more fillers, optionally one or more freeze-thaw agent, optionally one or more neutralizing agents, optionally one or more plasticizers, and/or combinations thereof.

摘要： The instant invention is a heat activated adhesive composition comprising an ultra-high solid polyurethane dispersion. The ultra-high solid polyurethane dispersion comprises (1) a first component comprising a first polyurethane prepolymer comprising the reaction product of a polyol and polyisocyanate, (2) a second component comprising a media phase selected from the group consisting of a second polyurethane prepolymer emulsion, a low solid content polyurethane dispersion, a seed latex, and combinations thereof; and (3) optionally a chain extender. The ultra-high solid polyurethane dispersion has at least a solid content of at least 60 percent by weight of solid content, based on the total weight of the ultra-high solid polyurethane dispersion, and a viscosity of less than 5000 cps at 20 rpm at 21° C. using spindle #4 with Brookfield viscometer.

摘要： Dispersions of hybrid polyurethane particles are made using miniemulsion techniques. An isocyanate-terminated prepolymer and a monomer are mixed and dispersed in an aqueous phase to form a dispersion of droplets. All droplets are polymerized and chain-extended in one step to form hybrid particles containing a polyurethane and a polymer of the monomer. This process provides a simple method of making hybrid particles, in which particle size and the number of particles is controlled in the mixing step. The hybrid particles often have a coreshell morphology, with the polyurethan being concentrated in the shell and the polymer being concentrated in the center of the particle.
