Quinizarin, also known as Quinoline, is an aromatic chemical compound primarily used in the production of dyes. It is also used in the production of photographic chemicals and as a preservative for paints and coatings.
Common types of failures when rubber is exposed to quinizarin include discoloration, cracking, and premature deterioration. This is due to the chemical’s ability to weaken and degrade rubber’s natural chemical bonds. Additionally, prolonged exposure to quinizarin can cause rubber to become more brittle and susceptible to tearing.
