Application and Uses
·
Wood Finish
Shellac is used
as a barrier or primer coat on wood to prevent the bleeding of resin or
pigments into the final finish, or to prevent wood stain from blotching.
Shellac varnish is simple and convenience for use. With the features of strong
force of adhesion, dry rapidly, smoothly coating, full of elasticity, uniform
luster, it is widely used in the wooden ware industry. Instead of using
methanol lacquer, Shellac varnish is applied more frequently in exclusive
furniture in recent years, because the methanol lacquer is toxic to human
beings. Shellac is the central element of the traditional “French polish”
method of finishing furniture and fine viols, guitars and pianos.

release. It is also used to replace the natural wax of the apple, which is
removed during the cleaning process.

stains blocker, and can provide an excellent barrier against water vapor
penetration. Shellac-based primers are an effective sealant to control odors

‘blues’, colors difficult to achieve with other fuel mixes in fireworks
formulae.
