SILICATE ESTERS Resistant O-Rings and Seals
Shellac, also known as silicate esters, is a resin secreted by the female lac bug. It is used in a variety of industries as a wood finish, electrical insulation, and in cosmetics. Common failures when rubber is exposed to shellac include swelling, hardening, and brittleness. Additionally, shellac can cause rubber to become brittle and weak, leading to cracking and crumbling with prolonged exposure.
