Styrenated Unsaturated Polyester & Vinyl Ester coatings are accepted for use in chemical immersion tank linings. The primary advantage is the increased chemical resistance to harsh commodities and fast turn around time compared to epoxy coatings. However, styrene is becoming heavily regulated due to its safety and health concerns. Styrene also has a pungent odor and contributes to the significant shrinkage in the coating wet film. Typical styrenated coatings often use wax in the top coat to acquire a tack free surface, but this presents a problem while attempting to recoat. The industry is seeking an alternative to styrenated coatings and through formulation and resin composition a styrene free coating can lead to unique properties. This report will outline two novel styrene free coating systems (SF Vinyl Ester Coating that will be referenced as Coating A and SF Vinyl Ester Novolac Coating that will be referenced as Coating B) that improve upon the drawbacks of styrenated coatings while maintaining similar performance.
