(1)Shellac dissolves in a wide variety of alkaline or rapidly drying alcoholic solvents, but is resistant to a number of other solvents, particularly hydrocarbons.
(2) Its films show excellent adhesion to a wide variety of surfaces, posessing high gloss, hardness and strength.
(3) Shellac is a powerful bonding material with low thermal conductivity and a small coefficient and expansion. Its thermal plasticity and capacity of absorbing large amounts of filters are noteworthy.
(4) Its electrical properties include high dielectric strength, low dielectric constant and characteristic freedom from tracking.
(5) It is resistant to the action of ultraviolet rays.
(6) Shellac is non-poisonous
