Title: Innovations by Purushoth Kesavan in Natural Stone Sealing

Introduction

Purushoth Kesavan, an innovative inventor based in Franklin Square, NY, has made significant contributions to natural stone sealing technology. With two patents to his name, he has developed advanced compositions that enhance the durability and resistance of natural stone surfaces.

Latest Patents

Kesavan's latest patents focus on natural stone sealer compositions. The first patent discloses a two-part composition specifically designed for sealing natural stone or masonry. This composition comprises a first part that includes polyvinylidene fluoride (PVDF) particulate, a low evaporation rate organic solvent, and water. The second part features a blend of various liquid resin formulations.

The second patent relates to polymeric compositions that are applied onto natural stone to offer long-term chemical, stain, and water resistance, along with antimicrobial properties. Many natural, unsealed stones lack the necessary resistance to stains, etching, or water. The compositions developed by Kesavan utilize chemical grafting technology involving prepolymers, monomers, catalysts, graft initiators, wetting agents, and antimicrobial agents. When these compositions are applied to stone surfaces, they create a graft polymerization that forms a chemically bonded polymer film, significantly enhancing the stone's protective properties.
