About Shellac

Origin:

Shellac is mainly produced in India and Thailand. Smaller quantities come from China and Vietnam. The product is manufactured in a process known since the old times as melting filtration. Nowadays hiqh-quality, dewaxed and decoloured Shellac is manufactured.

Components:

Raw Shellac (sticklac) contains 60-80 % pure Shellac, 4-6 % Shellac Wax and impurities such as splinters of wood, dead insects and moisture. Seedlac is washed and purified Sticklac and consists, according to its quality, of 85-90 % pure Shellac, 5-8 % Shellac Wax and 2-5 % impurities.

Packing:

Jute bags of 25 KGS or 50 KGS NETT
Paper bags of 25 KGS NETT
COTTON BAGS OF 25 & 50 KGS NETT.

Uses:

Wood Treatment (primers, high gloss and mat polishes); Electrics (insulators); Printing inks, inks and china inks; Cosmetics ( binder for mascara, shampoo, film former for hairspray, micro incapsulation of fragrances); Food (fruitcoatings, parting and glazing agent for confectionary and chocolates); Pharma (tablet coating); Abrasives (binder for grinding wheels); Dental; Hat manufacturing (for stiffening); Conditioning for wooden floors; Leather finishes; Pyrotechnics; Coating of seeds; Micro incapsulation of dyestuffs.

Shellac Wax:

Trade Names:

Origin:

4-6 % of the wax are only contained in crude Shellac and it is obtained as waste product during the manufacture of spirit lacquer and alcoholic solutions of Shellac.

Description:

The commercial qualities are hard, brown and have excellent shine-producing charac-teristics which can nearly be compared with those of Carnauba Wax.

Components:

Shellac Wax is mainly a mixture of esters (approx. 60 %) and free alcohol (approx. 35 %). Furthermore, small amounts of hydrocarbons, penta- and hentriacontanes and approx. 1 % laccic acid are contained.

Packing:

Paper bags

Application:

Polishes which normally consist only of paraffin and montan wax, give a highly shining surface if only a small amount of Shellac Wax is added; moreover as substitute for Candelilla Wax
