Title: Innovations of Shinjiro Hama
Introduction
Shinjiro Hama is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of polyurethane technology, holding a total of 2 patents. His work focuses on developing advanced materials that enhance the performance and usability of coatings and adhesives.
Latest Patents
Hama's latest patents include a self-emulsifiable polyisocyanate mixture and a one-component-type composition for polyurethane elastomers. The self-emulsifiable polyisocyanate mixture is characterized by a low hexamethylene diisocyanate monomer content and an average NCO functionality, which allows for excellent compatibility and stability when combined with water or water-soluble resins. This innovation results in an aqueous coating or adhesive composition that boasts superior heat resistance, workability, and adhesion to substrates.
The one-component-type composition for polyurethane elastomers comprises a polyurethane precursor that includes a polyisocyanate component and a compound with active hydrogen groups. This composition is designed to have storage stability comparable to thermoplastic elastomers, making it easy to handle and environmentally friendly. It is particularly useful for preparing elastomers with physical properties similar to those of two-component-type elastomers.
