Are anaerobics compatible with rubber parts the products may come in contact with in the liquid state prior to cure?
There are no long term studies for anaerobics and compatibility with various elastomers. There is a general consensus though that liquid anaerobics upon prolonged contact can negatively impact some elastomers in the form of swelling, cracking and weight change. Customers should carefully test products for compatibility. Some Loctite dispensing equipment utilizes Viton o-rings and seals specifically because this has been deemed suitable for use with anaerobics for a reasonable amount of time. Once an anaerobic cures, there is no compatibility concerns between rubber hardware and the cured, very inert plastic film/anaerobic.
