Benzocatechol, also known as catechol, is a naturally occurring aromatic organic compound with the chemical formula C6H4(OH)2. It is commonly used in the production of dyes, medicines, and as a preservative in products such as shampoos and cosmetics.
When rubber is exposed to benzocatechol, it can cause the rubber to weaken and become brittle. Over time, the rubber may start to crack or tear due to the softening of the material. The rubber can also become discolored or stained due to the chemical reaction. The rubber may also become swollen and distorted, making it difficult to use for sealing purposes. Synthetic rubbers such as EPDM and Nitrile are more resistant to benzocatechol than natural rubber.
