Latest Patents
One of Kosaka's latest patents is a coating composition for thick coatings. This composition is prepared by adding an aggregate to a coating liquid that contains 5 to 40% by weight of colloidal silica and 3 to 40% by weight of dissolved and/or finely dispersed organic polymer. The resulting mixture has an SiO.sub.2/M.sub.2 O mole ratio of at least 7 and a viscosity lower than 100 c.p. at 20°C when kept in a sealed state at 50°C for 10 days. This coating composition is particularly suitable for applications requiring a thickness of 1-20 kg/m², offering excellent stability and high water resistance, weather resistance, and adhesive strength without efflorescence on its surface.
Another significant patent by Kosaka is a process for preparing molds. This process involves creating a slurry of refractory powder in a binder solution that includes silica sol and monomethyl triethanol ammonium silicate or tetraethanol ammonium silicate. The method includes repeating an overcoating of the slurry and refractory powder, which results in the formation of a green mold that is subsequently separated from the pattern and calcined.
