Latest Patents

Sakugawa's latest patents include groundbreaking formulations aimed at improving the efficiency and effectiveness of siloxane compositions. His first patent focuses on **Fast-curing modified siloxane compositions**, which are composed of an alkoxy- or silanol-functional silicone intermediate, an amine reactive ingredient (such as acetoacetate or acrylate-functional ingredients), an epoxy-functional ingredient, and a curing agent. This unique combination allows for the creation of a fully cured protective film comprised of a cross-linked enamine polysiloxane and/or acrylate polysiloxane, notably reducing curing time compared to conventional epoxy siloxane compositions.

Additionally, he developed **Elastomer-modified epoxy siloxane compositions**, which combine a silicone intermediate with an epoxy resin and elastomeric resinous intermediate. This innovative composition not only promotes hydrolysis of polysiloxane but also enhances the cured product's properties, including impact resistance, flexibility, crack resistance, and abrasion resistance, surpassing the capabilities of conventional epoxy systems.
