Shellac Resin Powder50g


Shellac is a natural resin refined from Lac, the secretion of the tiny red Lac insect, Kerria lacca, which is parasitic on certain host trees in India.

Bleached Shellac is refined using the Bleaching Process, which involves dissolving Seedlac in an aqueous alkaline solution, such as sodium carbonate. The solution is then filtered to remove any insoluble material before being bleached with sodium hypochlorite to remove the colour. The Shellac is then precipitated from the solution by adding dilute sulphuric acid, before being filtered, washed with water and dried.
