Title: Innovations of Junichi Sueyoshi in Aqueous Coating Technologies

Introduction

Junichi Sueyoshi is a notable inventor based in Kyoto-fu, Japan. He has made significant contributions to the field of aqueous coating technologies, holding three patents that focus on recycling methods and compositions. His work is particularly relevant in the context of environmental sustainability and efficient resource management.

Latest Patents

One of his latest patents is a method for recycling aqueous paint. This innovative approach maintains material balance within a recycling system by controlling the liquid amount during the spray-coating process. The method involves coating an article with aqueous paint in a water-curtain-type booth, collecting over-spray paint through a water curtain, and separating the collected solution into condensed paint and filtrate using an ultra-filtration apparatus. This process ensures that the total amount of liquid in the recycling system remains constant during the coating operation.

Another significant patent by Sueyoshi is for a recyclable cold curing aqueous coating composition. This composition includes an oxidative-polymerizable, modified epoxy resin, anticorrosive pigments, and a drier. The resulting coating film exhibits improved water and corrosion resistance, allowing for repeated reuse through recycling and readjustment. This innovation not only enhances the performance of coatings but also promotes sustainability in the coating industry.
