Paper adhesive shellac

A protein derived from corn. It lacks the essential amino acids lysine and tryptophan. Commercially, zein is extracted from corn gluten meal with alcohol. In the food industry, its prime use is as an edible coating for foodstuffs such as nut meats and candy. In manufacturing, it has a variety of uses plastics, paper coatings, adhesives, shellac substitute, printing, laminated board, and microencapsulation. 

Natural resins are generally described as solid or semisolid amorphous, fusible, organic substances that are formed in plant secretions. They are usually transparent or translucent yeUow-to-brown colored, and are soluble in organic solvents but not in water. The principal uses for natural resins are in varnishes, printing inks, adhesives, paper size, and polymer compositions. The term natural resins includes tree and plant exudates, fossil resins, mined resins, and shellac. They often have been altered from their original state during isolation and processing. For some appHcations, the resins have been chemically modified to increase their industrial utiUty.

Candelilla wax and carnauba wax are mainly used for the production of candles. Carnauba wax can produce a glossy finish and as such is used in automobile waxes, shoe polishes and waxing skin. Carnauba wax is also used for the preparation of polishing waxes, carbon paper and many other purposes. Palm wax is the raw material for the production of wax candles and matches. Myrica wax and related waxes have found application in the pharmaceutical and food industries. Shellac is used to make paints, varnishes, sealing waxes, adhesives and in insulating materials.
