Shellac is a kind of non-toxic natural gum resin dissolves in a wide variety of alkaline or rapidly drying alcoholic solvents but is resistant to a number of other solvents particularly hydrocarbons. The low thermal conductivity and a small coefficient of expansion cause shellac to lead to a powerful bonding material. Our Machine made shellac products are produced in heat process by machine. Under heat process the separation of pure lac is achieved by melting. The molten lac is then stretched by means of rollers into long continuous sheet.
