Advanced coatings and coating lining systems are being increasingly used by industry to protect process equipment in challenging chemical environments. This includes not only severe corrosive liquors
encountered in many Chemical Process Industry streams, but also the high purity process liquors and rinse systems of the pharmaceutical and microelectronics industries. This paper will discuss the design options
for optimizing the performance of fluoropolymer-based coating systems for industry-specific applications such as these. Design factors discussed will include surface pre-treatment options, chemical and
mechanical bondhg systems, field-proven and advanced polymer barrier coatings, homogeneous and graded polymer banier stacks, and imbedded permeation barriers. The processing teqniques for applying
engineered coatings will be discussed since processing also plays an Important role in the design options available to individual coating applicators and ultimate performance of the coating system applied. Several case studies will be presented and discussed.
Keywords: coatings, engineered coatings, functional coatings, linings, fluoropolymers, corrosion resistance, high purity.
