Latest Patents

Tanya holds a patent for "Aqueous polyurethane dispersions and coatings prepared therefrom." This invention focuses on two- and three-component aqueous polyurethane compositions that are cured at ambient temperature. These compositions exhibit excellent chemical resistance without compromising abrasion resistance and flexibility. The two-component system includes a hydroxy functional aqueous polyurethane dispersion blended with phenoxy resin and a polyisocyanate. The three-component system incorporates 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 polyurethane solids in the dispersion, while the polyisocyanate mass is between 50 to 200% of the polyurethane solids. The resulting polyurethane compositions have a preferred mass fraction of solids between 10-50%.
