Shellac is a resinous substance, which is the secretion of the insect Laccifer. Shellac was formerly produced in large quantities mainly in South and Southeast Asia, and especially in India and Thailand. The annual production amounted to about 50.0000 tons. Around 300.000 insects are needed to harvest one kilogram of shellac.
Shellac is mainly used as primer or protective coating. Shellac is only suitable for indoor use.
