Title: Henry Stanley: Innovator in Urethane and Acrylic Technologies
Introduction
Henry Stanley is a notable inventor based in Cedar Grove, NJ (US). He holds a total of 6 patents that showcase his contributions to the fields of urethane and acrylic technologies. His innovative approaches have significantly impacted the development of waterborne adhesives and coatings.
Latest Patents
Among his latest patents, one is titled "Process for preparing urethane/acrylic-or-vinyl latexes." This method involves the preparation of polyurethane/acrylic-or-vinyl latexes for use in waterborne adhesives or coatings, ensuring that the urethane polymer component is free from urea linkages. The process includes preparing a fully reacted emulsifiable polyurethane in an acrylic or vinyl monomer, which serves as the solvent or diluent. The monomer and polyurethane are coemulsified, followed by the addition of free radical initiators to carry out a regular acrylic or vinyl addition polymerization.
Another significant patent is "Acrylic modified reactive urethane hot melt adhesive compositions." This invention enhances urethane prepolymers by adding low molecular weight polymers formed from ethylenically unsaturated monomers that lack active hydrogen. The result is a hot melt adhesive that can be coated at a viscosity of 3000 to 50,000 cps at 120°C without requiring additional tackifiers or plasticizers. This adhesive demonstrates improved initial cohesive strength and enhanced strength after aging of the cured bond.
