Sticklac
Sticklac is the resinous secretion of the lac insect, found on the branches of host trees.
Seedlac
Seedlac is the granular form of lac, created by crushing sticklac and removing the impurities.
Shellac Flakes
Shellac flakes are created by dissolving seedlac in alcohol and then allowing the liquid to evaporate, leaving behind thin flakes of shellac.
Aqueous Shellac
Aqueous shellac is a water-based solution of shellac, which is created by dissolving shellac flakes in water.

What is the difference between SWANLAC Dewaxed Bleached Shellac powder and AFS 701 Dewaxed Shellac flakes?
SWANLAC Dewaxed Bleached Shellac powder is manufactured by the chemical bleaching process where sodium hypochlorite is used for reducing the water insoluble colours. Dewaxed Shellac flakes are manufactured by the solvent extraction process where activated carbon is used for the same purpose.
How is Shellac applied?
Shellac comes in various forms- powder, flakes, aqueous etc. It is readily soluble in many solvents like ethanol, IPA etc. It can be dissolved in water by using a suitable base. Shellac can be applied by spraying, dipping, brushing, padding, rolling, sponging and any other suitable form. Tablets can be coated by a perforated/ side vented coating machine and fluid bed can be used for smaller particles.
What is SWANLAC ASL 10 aqueous shellac solution and how is it different from traditional Shellac?
Shellac is insoluble in water but aqueous shellac solutions can be prepared by using a suitable base. SWANLAC ASL 10 is the aqueous shellac solution manufactured by A.F. Suter. It is 25% Shellac and 75% Demineralized Water. There are no preservatives or VOC and it is a 100% Natural product.
What is the advantage of using SWANLAC ASL 10 aqueous shellac solution as compared to a shellac dissolved in alcohol?
The major advantage of SWANLAC ASL 10 is that it does not contain volatile substances and is environment friendly. Also shellac solution in alcohol undergoes esterification over time which causes several problems like tackiness, performance loss, limited shelf life etc. Such problems are avoided in an aqueous shellac solution.
