Blonde

Dewaxed Shellac ? Blonde Grade is a premium natural resin known for its slightly warmer hue and outstanding film-forming capabilities. Manufactured through Sitaram Saraf?s precise solvent extraction and dewaxing process, this grade offers a light golden tone while maintaining high purity, low wax content, and excellent solubility. Its slightly higher color index compared to Super Blonde makes it ideal for applications that require a natural resin with a touch more visual depth without compromising clarity or performance. Blonde Grade is widely favored across cosmetics, food coatings, pharmaceuticals, and wood finishing for its balance of aesthetic warmth and technical functionality.
