Latest Patents

Hatta's latest patents include:

1. **Prepreg of Epoxy Resin, Hardener, and Organodialkyurea Promoter**: This patent describes an epoxy resin composition that contains a matrix of an epoxy resin with multiple epoxy groups per molecule. It incorporates a phenolic hardening agent with multiple hydroxyl groups, an organobis(N-dialkylurea) hardening promotion agent, a solvent for this hardening promotion agent, and a guanamine compound. The invention aims to create a prepreg that excels in preservation stability while reducing solvency erosion caused by plating solution infiltration.

2. **Process for Manufacturing Prepregs for Use as Electric Insulating**: This patent outlines a method for producing a prepreg designed for electrical insulation. It involves the rapid mixing of a main epoxy resin and a subsidiary resin containing a hardener. The mixing is followed by coating a reinforcing member with a thin film of the mixture using a die coater under specified conditions. The process includes non-contact heating to impregnate the member with the resin and additional steps to semi-harden and compact the resin, leading to the continuous manufacturing of a sheet-like fiber-reinforced composite material.
