Lac is the raw material of Shellac. Our modern, semi-automatic plant is located at Village & P.O. Bundu, District-Ranchi in Jharkhand (India), which is the finest Lac growing area in the world. These finest quality Lac is processed and manufactured into finished product known as Shellac and other Lac products under strict quality control and personal supervision of our Senior Partner, Mr. Binay Kumar Gupta. The raw material and finished products are thoroughly checked and tested in our laboratory at our plant and also by other approved laboratories.

We manufacture both Handmade and Machine made grades of Shellac, Buttonlac, Seedlac, Natural Lac Dye and other Lac products. Our monthly production capacity is 100 M/Tons. Our main machine made grades are as follows:
GB-TN SHELLAC
GB-LEMON SHELLAC
GB-ORANGE SHELLAC

Natural Lac Dye produced by us, is non-toxic, eco-friendly and free from banned AZO group. It is only natural dye amongst all the dyes which can produce dozens of shades by using different mordants which no other natural dye can do.

What is Lac & Shellac?
Lac is the resinous secretion of the Lac insect, known as Laccifer Lacca, a parasite that forms incrusation on the branches of certain trees. On completion of incrustation, it is separated from the branches either by breaking by hand or scraping with a knife. Lac in this form is known as Sticklac and brought to Shellac processing plant for refining and processing.

Seedlac: It is a semi-processed product derived after washing crushed Sticklac with water. This product is in granule form and is a raw material for manufacturing different grades of Shellac, Buttonlac and Bleached Lac, Dewaxed shellac & Aleuritic Acid etc. Seedlac in granule form is also exported, which is mainly used for processing Bleached Lac for use in colourless polishes and nitrocellulose lacquers.

Lac Dye: When Sticklac is crushed and washed with water, the water-soluble Lac Dye is dissolved out in small quantity after several processes. This Dye is purely natural and hence called Natural Lac Dye.

Shellac: Seedlac is processed into Shellac flakes by melting it. This is done mechanically, as well as by hand process. When processed mechanically, it is known as Machine Made Shellac and when by hand process, it is called Hand Made Shellac. Machine Made Shellac is manufactured in large quantity, compared to Hand Made Shellac.

Button Lac: When Seedlac is melted by hand process, it is also processed into round Button form known as Buttonlac.

Bleached Lac: Lac is bleached by the use of Sodium Hypochlorite solution. Bleached lac is manufactured for use in colourless polishes and nitrocellulose lacquers.

Dewaxed and Decolourised Shellac: Lac after wax extraction is known as Dewaxed Lac or Wax free Lac. It is derived by solvent process. Very high grade of Shellac, which is Dewaxed & Decolourised Shellac, is obtained by this method, by using activated carbon as the Decolourising Agents.

Properties of Shellac and other Lac products
Shellac is used in different industries for the following different properties:

• Shellac dissolves in a wide variety of Alkaline or rapidly drying alcohol solvents, but is resistant to a number of other solvents, particularly hydrocarbons.
• Its films show excellent adhesion to a wide variety of surfaces, possessing high gloss, hardness and strength.
• Shellac is powerful bonding material with low thermal conductivity and a small coefficient of expansion. Its thermal plasticity of absorbing large amounts of fillers is noteworthy.
• Its electrical properties include high dielectric strength, low dielectric constant and characteristic freedom from tracking.
• It is resistant to the action of ultra-violet rays.
• Shellac is non-toxic.
