Latest Patents
One of Smith's latest patents is for durable repellent fluorochemical compositions. This invention provides compositions for treating fibrous substrates to render those substrates durably repellent to water and oil, as well as durably resistant to dry soil. The process involves reacting a tri- or higher order isocyanate with a fluorochemical alcohol, followed by a reaction with water and a difunctional poly(oxyalkylene)-containing material. Additionally, the method includes applying the composition to fibrous substrates along with hydrophilic anti-staining compounds.
Another significant patent by Smith is for aqueous oil and water repellent compositions that cure at ambient temperatures. These fluorochemical compositions are designed for treating textile fibers and fabrics to impart oil and water repellency without the need for thermal treatment. The compositions consist of a solution or dispersion of a fluorochemical acrylate copolymer and a polyalkoxylated polyurethane with pendant perfluoroalkyl groups.
