A Corrosion Resistant Non Reactive CVD Coating That Prevents Metal Ion Contamination

What Is Silcolloy?

Silcolloy® is a corrosion resistant coating process that is bonded to stainless steel and other surfaces by chemical vapor deposition.  Our patented high tolerance silicon barrier coating technology protects the most intricate precision components in corrosive and harsh environments for rust prevention, metal ion contamination prevention and improved durability.  Silcolloy increases the lifetime of components up to 10x or more in acidic environments including hydrochloric acid, nitric acid, HBr, ferric chloride, and sea water.
