Latest Patents

Among Ohashi's latest patents, two inventions stand out for their innovative methodologies and practical applications. The first patent, titled "Method for preparation of aqueous emulsion of long-chain alkyl-modified silicone," discloses a novel technique that allows for the efficient preparation of an aqueous emulsion of organopolysiloxane with long-chain alkyl groups bonded to silicon atoms. Unlike traditional methods, which require pre-modification of the silicone before emulsification, Ohashi's technique co-emulsifies an organohydrogenpolysiloxane with a long-chain α-olefin compound. This process, under the influence of a catalytic platinum compound, facilitates an in situ hydrosilation reaction, leading to an exceptionally stable emulsion, which withstands long-term storage, dilution, and mechanical stress.

The second significant patent is related to the "Base fabric for air bags and method for the preparation thereof." This invention focuses on enhancing the performance of automobile air bag fabrics. The fabric combines excellent flexibility, allowing for compact folding, with high flame retardancy, ensuring safety in hazardous situations. The material composition involves a woven fabric web coated with a silicone-based composition in the form of an aqueous emulsion.
