Title: Douglas Ronald Chambers: Innovator in Aqueous Polyurethane Technology
Introduction
Douglas Ronald Chambers is a notable inventor based in Hunterville, NC (US). He has made significant contributions to the field of polyurethane technology, particularly through his innovative patent related to aqueous polyurethane dispersions and coatings.
Latest Patents
Chambers 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 consists of a hydroxy functional aqueous polyurethane dispersion blended with phenoxy resin, along with a polyisocyanate as the second component. 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 typically ranges from 1 to 50% of the mass of the polyurethane solids in the dispersion, while the polyisocyanate mass can be between 50 to 200% of the polyurethane solids. The resulting polyurethane composition has a preferred mass fraction of solids between 10-50%.
