Title: Innovator Sathanjheri A Ravishankar: Pioneering Advances in Pigment Technology

Introduction

Sathanjheri A Ravishankar, based in Macon, GA, is an inventive force with a strong track record in the field of pigment technology. With three patents to his name, Ravishankar has made significant contributions that enhance the efficiency and quality of materials used in various industries, particularly in coatings and printing applications.

Latest Patents

Ravishankar's latest innovative work includes two notable patents. The first, titled "Kaolin clay glossing pigment and preparation thereof," involves the creation of novel nanosized kaolin clay particles. By agitating fine particle size fractions of kaolin clay in a Netzsch mill, he successfully reduces particle size while decreasing aspect ratio and increasing surface area. These ultrafine kaolin particles are especially advantageous as pigments, providing high surface gloss to inkjet printing papers.

His second patent, "Composite aggregate pigments for the coating industry," outlines a process to produce composite aggregate pigments (CAPs) that possess superior optical and dispersion characteristics. This technique involves aggregating titanium dioxide and calcined clay with zirconium hydroxy complex chemicals within a specific pH range. After being heat-treated post-production, these pigments exhibit enhanced optical properties. Additionally, by incorporating a small amount of a rod-shaped pigment, such as wollastonite, Ravishankar creates multi-faceted pigments that offer exceptional quality.
