Title: The Innovations of Steven Hugh Ashdown
Introduction
Steven Hugh Ashdown is a notable inventor based in Darlington, GB. He has made significant contributions to the field of paint technology, holding a total of 2 patents. His work focuses on developing advanced materials that enhance the performance and application of paints.
Latest Patents
One of Ashdown's latest patents is for a gloss emulsion paint. This innovative aqueous gloss emulsion paint comprises a dispersion of structured composite particles. These structured particles consist of an association of inorganic pigment particles and polymeric particles. The polymeric particles are formed from a polymer or copolymer with a minimum film-forming temperature not exceeding 50 degrees Celsius. The component particles are held together due to surface charges, with the charges on the polymeric particles being of opposite sign to those on the inorganic pigment particles. The ratio of polymeric particles to inorganic pigment particles in the composite is maintained between 0.5:1 and 6:1 by volume.
Another significant patent involves treated titanium dioxide. This pigmentary material consists of particulate titanium dioxide particles that have been treated with a polymeric hindered amine stabilizer. The stabilizer is a polymer that is largely free of acidic groups and contains hindered amine stabilizing groups, which make up at least 35 percent by weight of the polymer. Additionally, the titanium dioxide particles may be treated with organic compounds such as polyhydric alcohols, alkanolamines, polysiloxanes, or fatty acids.
