Title: Osamu Kitoh: Innovator in Thermosetting Sealers
Introduction
Osamu Kitoh is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of thermosetting sealers, holding a total of 2 patents. His innovative work focuses on creating effective sealing solutions that enhance durability and performance.
Latest Patents
Kitoh's latest patents include a thermosetting highly foaming sealer and a thermosetting foaming sealer. The thermosetting highly foaming sealer is designed to fill gaps between two parallel planes. It contains an unvulcanized rubber, a vulcanizing agent, a softener, and an inorganic filler. This sealer is unique in that it expands from 1 to 2 times its original volume when heated and vulcanized. Additionally, a second sealing member can expand 6 times or more, ensuring that the gap is securely filled without running down or slipping off, even on vertical surfaces. This innovation effectively prevents dust and water intrusion, providing excellent rustproofing capabilities.
The thermosetting foaming sealer is another remarkable invention by Kitoh. It is specifically designed to fill vacant spaces and comprises a foaming substance that matches the shape of the space to be filled. A restraining substance, which is an elastomer with high viscosity at room temperature, maintains the compressed state of the foaming substance. During paint film baking, the restraining substance becomes less viscous, allowing the foaming sealer to fill the vacant space effectively. This invention has been particularly beneficial in achieving desired silence levels in automobiles.
