MIXED ACID ETCHANTS Resistant O-Rings and Seals
Mixed acid etchants are also known as mordants and are commonly used in printing, dyeing, and photographic processes. They are also used as metal etchants, to remove rust and corrosion from metal surfaces.
When rubber is exposed to mixed acid etchants, it can become brittle and harden, resulting in a decrease in its flexibility and elasticity. Furthermore, the acidity of the etchant can cause the rubber to degrade over time, leading to cracks and other forms of physical damage. Additionally, the acidity can cause corrosion of the rubber, which can weaken its structural integrity and increase the risk of failure.
