Title: Akio Ishiwatari: Innovator in Cross-Linking Compositions
Introduction
Akio Ishiwatari is a notable inventor based in Onoda, Japan. He has made significant contributions to the field of cross-linking compositions, holding two patents that showcase his innovative approach to materials science.
Latest Patents
Ishiwatari's latest patents include a composition of cross-linking peroxides that exhibit excellent storage stability. This composition prevents the exudation of peroxide while maintaining a high concentration of the organic peroxide, making it easily blendable with rubber for cross-linking applications. The process involves mixing a softening agent with a Brookfield viscosity of 10,000 poises or less at 60 °C with an organic peroxide, preferably in the presence of a filler and optional additional ingredients. Another significant patent is for an unsaturated alkyd-containing organic peroxide composition. This curing agent composition contains 20-90% of an unsaturated alkyd diluent that remains fluid at room temperature. It is particularly useful for curing unsaturated polyesters, addressing the issue of harmful phthalate diluents bleeding from cured polyesters while ensuring excellent stability of the diluted peroxide.
