Title: Inventor Shigehiro Kawahito: Innovating Coating Materials

Introduction

Shigehiro Kawahito, an accomplished inventor based in Soka, Japan, has made significant contributions to the field of coating materials. With a remarkable seven patents to his name, he has developed innovative solutions that enhance the quality and functionality of water-based paints and coatings.

Latest Patents

Among Shigehiro Kawahito's latest patents is an additive specifically designed for aqueous coating materials that imparts distinctness of image to the coating film. This additive remarkably improves the distinctness of glossy aqueous coating materials, effectively preventing the white blurring phenomenon caused by the diffuse reflection of light. By increasing the dispersivity of carbon black or organic pigments in the coating material resin, this innovation has achieved a level of performance that was previously unattainable. The use of catecholic polymer black microparticles, which exhibit angle-independent structural color, further enhances the distinctness of the image.

Another notable patent from Kawahito is a defoaming agent for water-based paint. This innovative formulation effectively eliminates foams generated during the preparation, coating, drying, and baking processes of water-based paint. The defoaming agent is unique in its ability to operate independently without the need for other defoaming agents, all while preserving the appearance of the baked coated film and ensuring recoatability. The composition comprises polyoxyethylene hydrogenated castor oil triisostearates and polyalkyl vinyl ether or similar compounds dissolved in liquid paraffin.
