Description

Waxes And Waxy Substances, Shellac is a refined natural resin of high commercial importance, primarily derived from the secretions of the lac insect. This versatile material serves as a critical film-forming agent, sealant, and glazing agent across multiple industries, valued for its excellent adhesion, gloss, and protective properties. Key industrial buyers include manufacturers in the food, pharmaceutical, confectionery, and surface coating sectors who require a natural, compliant, and reliable ingredient for their formulations.

Application

• Pharmaceutical Coating: Used as an enteric or sustained-release coating for tablets and pills, providing a protective barrier.
• Food Glazing & Confectionery: Applied as a glazing agent on candies, chocolates, and chewing gum to provide shine and prevent sticking.
• Fruit & Vegetable Coating: Used to create a protective, shiny coating on fresh produce to extend shelf life and enhance appearance.
• Surface Finishes: A key component in wood polishes, varnishes, and lacquers, offering a durable, high-gloss finish.
• Microencapsulation: Acts as a wall material for encapsulating flavors, fragrances, and active ingredients.
• Electrical Insulation: Employed in traditional electrical applications as an insulating resin.
• Printing Inks: Used as a binder and gloss enhancer in specialty printing inks.
• Adhesives & Sealants: Functions as a natural binder in specific adhesive and sealing compound formulations.
