Silcolloy® is a corrosion resistant coating 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.
Coat flow path surfaces to improve corrosion resistance, prevent metal ion contamination and to improve product yield.
Improve component durability and reduce maintenance cost by coating instrument probes, tubing, valves and fittings.
Apply Silcolloy to critical surfaces to prevent metal interaction with analytes. Coat reactors, instrumentation components, stainless steel, glass, and ceramic flow path components.
Coat flare and stack probes, tubing, fittings, and sample cylinders to improve test reliability and prevent regulatory compliance issues.
Silcolloy is a high purity barrier coating for corrosion and oxidation resistance
The Silcolloy CVD coating process bonds a thin and flexible silicon layer to even the most complex geometries, including face seal, conflat, and compression sealing surfaces. Silcolloy's oxidation resistant and corrosion resistant surface is the logical choice for protecting and enhancing critical flow paths and preventing surface interaction with product. Silcolloy remains stable and contaminant free under the most extreme conditions assuring long lasting corrosion resistance. Comparative studies show Silcolloy outperforms common steel alloys, providing super alloy corrosion resistance at a fraction of the cost.
