Latest Patents

David LeBlanc holds a patent for "Aqueous polyurethane dispersions and coatings prepared therefrom." This invention is directed towards two- and three-component aqueous polyurethane compositions that are cured at ambient temperature. These compositions demonstrate excellent chemical resistance without compromising abrasion resistance and flexibility. The two-component system consists of a hydroxy functional aqueous polyurethane dispersion blended with phenoxy resin, along with a polyisocyanate. The three-component system includes a hydroxy functional aqueous polyurethane dispersion, an epoxy resin, and a polyisocyanate. The mass of the epoxy or phenoxy resins ranges from 1 to 50% of the mass of the polyurethane solids in the dispersion, while the mass of the polyisocyanate is between 50 to 200% of the mass of the polyurethane solids. The resulting polyurethane composition has a mass fraction of solids preferably between 10-50%.
