FC 43 is a common chemical used in a variety of industries such as automotive, engineering, construction, and aerospace. It is also known by other names such as F22, F502, and F316.
Common uses for FC 43 include providing a sealant for joints and connections, lubricating moving parts, and providing a waterproofing agent. When rubber is exposed to FC 43, common failures include discoloration, cracking, reduced flexibility, and weakening of the rubber material. In extreme cases, this can lead to the rubber material becoming brittle and breaking. In order to prevent these types of failures, it is important to use the correct type of rubber material that is resistant to FC 43 and other chemicals.
