Latest Patents
One of his latest patents is titled "Slurry composition and method for polishing organic polymer-based ophthalmic substrates." This invention provides a slurry composition that includes an aqueous dispersion of abrasive particles and a pyrrolidone compound. The abrasive particles can be alumina, zirconia, silica, titania, or combinations thereof. This innovative slurry composition is particularly effective for polishing organic polymer-based ophthalmic substrates with an index of refraction greater than 1.498, as it removes materials more efficiently than conventional compositions without compromising surface quality.
Another notable patent is "Slurry composition and method of use," which presents an aqueous slurry composition comprising cerium oxide and/or cerium oxide-containing mixed rare earth oxide abrasive particles, a polyacrylate, and an agent that retards hard settling. This composition is designed to polish glass and glass ceramics at a high removal rate while preventing hard settling upon extended static conditions, allowing for easy resuspension. The method of polishing a glass or glass ceramic substrate using this slurry composition is also detailed in the patent.
