Fluoroethylene vinyl ether (FEVE) resins were developed to overcome some of the problems associated with the use of fluoropolymers in coatings. These resins, which yield topcoats with lifetimes exceeding 60 years, can be cured at ambient temperatures for field applications, or at elevated temperatures in the shop. New FEVE resins have been developed to enable formulators to meet air quality regulations while still producing coatings with excellent durability.
The coatings industry is very familiar with shot/grit blasting as a mechanical means of surface preparation. Over the years, operators have worked with manual and automatic blast equipment with its associated dust collection arrangements. The industry is highly competitive, and control on operating costs is critical. Therefore, coaters are always on the lookout for ways to tune their process by lowering costs and increasing productivity.
The creepage of corrosion underneath a coatings film applied to a steel test panel is often used as a performance test for the anti-corrosion properties of a coating system. Underfilm corrosion creep, also sometimes referred as scribe creep in the laboratory environment, is defined as the degree of corrosion emanating away from a scribe line underneath a coating film applied to a steel substrate.
