Thin-Film Linings and Coatings
Thin-film linings and coatings, by definition, are films that are less than 20 mils (0.020″) in thickness.
These are generally spray-applied systems and can be used as lining systems when properly applied and holiday-tested. These can also be applied as an external coating system for protection of equipment in fume, splash, and spill exposure.
Thin-film systems used as linings require a higher standard of surface preparation than those used as external coating systems. Equipment design and fabrication quality are key in achieving a continuous lining system free of voids or defects that can adversely affect long-term performance. These lining systems are generally designed for immersion in mildly-corrosive chemical solutions, or in situations where product purity or product release is a critical factor.
Typical thin-film lining systems include:
- Baked phenolics
Typical thin-film coating systems include:
- Inorganic and organic zinc primers
- High-heat silicones
