Premium Quality Platina Dewaxed Shellac for Export by Sitaram Saraf

Platina

Dewaxed Shellac ? Platina Grade is the highest purity shellac offered by Sitaram Saraf, known for its exceptional clarity, light color, and versatile functionality. It is produced using a solvent extraction method, followed by an activated carbon treatment to achieve its distinct platinum-like transparency. This process effectively removes waxes and other impurities, resulting in a shellac grade that is color-stable, physiologically safe, and suitable for even the most sensitive applications. The Platina grade is highly valued across industries for its superior film-forming abilities, glossy finish, and excellent adhesion to diverse substrates, including human hair and biological surfaces. Its non-toxic nature and compatibility with various solvents and alkalis make it an indispensable resin in cosmetics, pharmaceuticals, food coatings, and specialty chemical formulations. As the lightest and most refined shellac grade, Platina is ideal for applications requiring minimal coloration, high purity, and rigorous performance standards.
