Title: Innovations by Tapan K Deb Roy

Introduction

Tapan K Deb Roy is an accomplished inventor based in Novi, MI (US). He holds three patents that showcase his expertise in the field of cathodic electrocoat technology. His work has significantly contributed to advancements in coating processes and materials.

Latest Patents

One of his latest patents is titled "Oxime blocked isocyanate cross-linker for cathodic electrocoat." This invention involves oxime blocked polyisocyanate cross-linking agents designed for use with amine epoxy resin adducts in cathodic electrodeposition processes. The oxime blocking agents are derived from acyclic aliphatic carbonyl-containing compounds with at least seven carbon atoms and hydroxylamine. The resulting oxime blocked polyisocyanates yield cathodic electrodeposited coatings that are smoother than those produced by previously known oxime blocked polyisocyanates.

Another significant patent is "High build, low bake cathodic electrocoat." This invention focuses on cathodic electrodepositable resin compositions that are particularly suited for film-forming applications in cathodic electrodeposition processes. The resin is created by reacting a polyepoxide with a water-soluble or water-miscible polyol, an excess of polyamine, and an aliphatic monoepoxide. When combined with a cross-linking agent and solubilized in an aqueous electrodeposition bath, this resin can deposit high build coatings quickly and at low cross-linking temperatures.
