Silcolloy coatings offer the highest temperature stability of all SilcoTek® solutions while simultaneously preventing corrosion and contamination from metal, glass, and ceramic substrates. These coatings are made up of several layers of high-purity silicon (Si), the same material used to make semiconductors, which provides a dense film that effectively shields coated parts from their process environment. Silcolloy is widely used as a solution to improve the chemical compatibility of various materials and help stainless steel perform like corrosion resistant superalloys, creating significant cost savings for customers in semiconductor, laboratory, energy, and many other industries.
Like all SilcoTek coatings, Silcolloy surfaces are applied using SilcoTek’s proprietary chemical vapor deposition (CVD) technology. Unlike typical liquid spray or dip coating methods, CVD is a completely non-line-of-sight process that uses gases at high temperatures to produce ultra-thin coatings which bond molecularly to the part substrate, creating superior adhesion compared to any other coating. This also means that even sub-micron sized openings, sharp edges, flexible components like bellows, and high aspect ratio flow paths are completely coated without requiring design changes.
