Our Dewaxed Shellac is the most renowned in the market due to genuine quality. With the finest quality, timely delivery of orders and most nominal prices in the market, we clasp the major segment of the market as compared to other bleached shellac Manufacturers and Exporters in India.

Dewaxed Bleached : Seedlac is dissolved in an aqueous-alkali solution, filltered, dewaxed and bleached with Sodium Hypochlorite to the desired color. The shellac is then precipitated from the solution with Sulphuric acid and dried. 

Aleuritic Acid (Shellac Aleuronic Powder) : Aleuritic Acid (9, 10, 16-trihydroxypalmitic acid), obtained from shellac by Saponification, is a unique acid containing three hydroxyl groups of which two are of adjacent carbon atoms.

Chemical Properties :

• Shellac dissolves in a wide variety of alkaline or rapidly drying alcoholic solvents, but is resistant to a number of other solvents, particularly hydrocarbons.
• Its film show excellent adhesion to a wide variety of surfaces, possess high gloss, hardness and strength.
• Shellac is a powerful bonding material with low thermal conductivity and a small coefficient of expansion. Its thermal plasticity and capacity of absorbing large amounts of fillers are noteworthy.
• Its electrical properties include high dielectric strength, low dielectric constant and characteristic freedom from tracking.
• It is particularly resistant to ultra-violet rays. Seedlac is dissolved in an aqueous-alkali solution, filltered, dewaxed and bleached with Sodium Hypochlorite to the desired color. The shellac is then precipitated from the solution with Sulphuric acid and dried.
