Shellac is a thermosetting natural resin produced by lac insects on the shellac tree that suck and digest the sap and then condense and dry the secretion on the tree. Shellac is boiled in water to dissolve part of the colored substances, and the yellow-brown flakes obtained are shellac sheets. The chemical composition of shellac is relatively complex. The main components are some resin-like substances of a mixture of hydroxycarboxylic acid lactones and lactides. The average relative molecular weight is about. The main components of alkaline hydrolyzate are - trihydroxyhexadecanoic acid and tricyclic sesquiterpene acid. In addition, there are various long-chain hydroxy fatty acids such as hexahydroxytetradecanoic acid.
Shellac is insoluble in water and acid at room temperature and soluble in organic solvents such as alcohol (heated at ℃ for hours but insoluble in alcohol). It dries quickly to produce a glossy and durable film that displays a high degree of adhesion to the surfaces of various objects. Strong and flexible. Therefore, it is waterproof, moisture-proof, rust-proof, corrosion-resistant, and protects objects. Resistant to ultraviolet light.
It can form a good film with high adhesion in alkaline solution.
Can resist hydrocarbon solvents such as gasoline and has oil resistance.
It is a low-heat non-conductor with a small expansion coefficient and a good insulator.
Appearance: light yellow fragments
