Wilckens EPOSIST 2000 SI is a high-volume solid epoxy anti-corrosive multi-purpose primer with self-indicating (SI) technology. This product can be specified for above and below water areas. The primer can be overcoated with various kinds of finishes. EPOSIST 2000 SI is distinguished by its unique and patented self-indicating technology that enables the applicator to visually confirm that the correct film thickness has been applied by checking the color development during the application process. The full Buff color is realized only when the correct dry film thickness has been applied. Therefore, any areas of low film thickness can easily be detected by visual inspection.
