Storage Condition | −20°C |
brown, brown-yellow to orange-yellow granules or flakes, friable and hard, slightly transparent. Odorless, tasteless, non-toxic. Soluble in ethanol, ether, ammonia, turpentine, soda ash or other alkali solution. Melting point of 115~120 ° C, can emit a special aromatic odor. In the case of long-term storage or heating, the polymerization will occur, so that the resin molecules become larger and larger, the viscosity increases, the softening point increases, and the fluidity deteriorates. The polymerization of shellac can be accelerated by adding a small amount of urea. Adding 2% ~ 3% urea to the semen of shellac wine can improve the hardness, elasticity, abrasion resistance, water resistance and adhesion of the paint film. Shellac has good mechanical, thermal and electrical properties.
shellac is a resin-like substance (purple stalks) secreted by shellac parasitic on soybean meal or mulberry plants, which is the original gum after removing impurities such as branches, and then crushed, hot-melted, it is made by filtering and other processes.
widely used in wooden furniture, Radio wood shell, double, sewing machine sticky board, wooden toys, Wood ruler and other surface protection, but also increase the gloss. It can also be used as electrical insulation materials, food additives and adhesives.
