Who would have thought…. Shellac primer is made primarily from shellac, a natural resin secreted by the female lac bug on trees in India and Thailand. The resin is collected, processed, and dissolved in alcohol to create the shellac used in primers. Shellac primers also contain other ingredients like alcohol (typically denatured), to act as a solvent, and additional binders or pigments to improve adhesion and coverage. These primers are often used for sealing stains, knots, and odors on surfaces
