Shellac CAS 9000-59-3
Shellac has excellent properties such as moisture proof, corrosion prevention, rust prevention, oil resistance, electrical insulation and thermoplastic. The best solvent for shellac tablets is low-grade alcohols containing hydroxyl, such as methanol and ethanol. Insoluble in glycol and glycerol, soluble in lye, ammonia, but also soluble in lower carboxylic acids, such as formic acid and acetic acid, insoluble in fats, aromatic hydrocarbons and their halogen derivatives, carbon tetrachloride, water, sulfur dioxide aqueous solution. Shellac resin is degradable in the natural environment. Discharge into the water will cause an increase in oxygen content of water organisms, make the water eutrophication, and sensorially make the water red.

1.In the food industry, shellac is also used in fruit fresh-keeping coatings to form bright films, prolong the shelf life of fruits, and increase their commercial value. Shellac is used in confectionery and pastry coatings to increase brightness, prevent moisture regain, and smear the inner walls of metal cans to prevent food from coming into contact with metal.
2.Shellac can be widely used in food, medicine, military, electrical, ink, leather, metallurgy, machinery, wood, rubber, and other industries.
3.Shellac paint has strong adhesion and is used in many high-grade woodware and decorations.
4.Shellac is used in the leather industry as a bright and protective finish, characterized by fast drying, strong filling, and strong adhesion to leather, making it softer and more elastic.
5. In the electrical industry, shellac is also used in the manufacture of insulating paperboard, laminated mica boards, ground electrical insulators, insulating varnishes, bulbs, fluorescent lamps, and solder pastes for electronic tubes.
6.In the military industry, shellac is mainly used as a retarder for coating agents, insulating materials, and gunpowder drugs. Shellac is also used to manufacture military equipment that is UV- and radiation-proof.
7.Shellac mainly used as a surface coating or filler for rubber products in the rubber industry. Improve wear, oil, acid, water, and insulation. Slow down the aging process and extend the lifespan.
