  • Shellac is a powerful bonding material with low thermal conductivity and a small coefficient of expansion. Its thermal plasticity and capacity of absorbing large amounts of fillers are noteworthy.
  • Its electrical properties include high dielectric strength, low dielectric constant and characteristic freedom from tracking.
  • It is particularly resistant to ultra-violet rays. Seedlac is dissolved in an aqueous-alkali solution, filltered, dewaxed and bleached with Sodium Hypochlorite to the desired color. The shellac is then precipitated from the solution with Sulphuric acid and dried.
