Shellac
MJ57 Dewaxed Decolored SHELLAC Flakes
Shellac is the general term for the refined natural polymer lac. Shellac
composition and quality depend on the raw material used and the refining
process. Our natural shellac flakes MJ57 are a dewaxed shellac, decolorized by
a solvent extraction process. The raw material is the secretion of the insect
Kerria yunnanensis.
