Pure One Buttonlac is a premium grade of hand-made shellac crafted through traditional processing methods that prioritize purity and functionality. Using high-quality seedlac, the production involves manually pressing molten lac through a cloth filter and shaping it into button-like discs. This traditional method, maintained through artisanal expertise, preserves the natural integrity and unique qualities of shellac, ensuring its suitability for diverse industrial, pharmaceutical, cosmetic, and food-related applications.
What sets Pure One Buttonlac apart is its slightly higher tolerance for insoluble matter while still maintaining the strict standards required for use in critical applications. With a medium-deep color index (up to 12), it offers a balance between purity, cost-effectiveness, and functionality. Its natural resin composition, film-forming capabilities, non-toxicity, and biodegradability make it an eco-friendly alternative to synthetic polymers in coatings, finishes, and encapsulations.
