Latest Patents
Knight's latest patents focus on innovative processes for preparing composite pigmentary materials. The first patent describes a method for creating a structured composite pigmentary material by forming a dispersion of uncoated titanium dioxide particles. This process involves cross-flow filtration to concentrate the titanium dioxide, which is then mixed with chemically distinct particles. The resulting composite material exhibits higher opacity and improved durability compared to conventional paints.
The second patent outlines a process for producing a structured composite pigmentary material in the form of a dispersion. This involves mixing an aqueous dispersion of inorganic pigmentary particles with an aqueous dispersion of polyvinyl chloride (PVC) particles. The interaction between the positively charged inorganic pigment particles and negatively charged PVC particles, stabilized by a surfactant system, results in a product that offers enhanced opacity and gloss compared to traditional pigments.
