70% PVDF resin-based coatings include standard color two-coat systems, consisting of a primer and color coat. Two-coat mica systems, also consisting of a primer and color coat. Three-coat and four-coat systems for metallic and exotic colors. These systems include a clear top coat and sometimes a barrier coat.
