All coatings are developed for standard flat sheet application.
Coatings formulated for internal application act as primers for the adhesive that affixes the sealant compound. PPG makes organosol-based coatings for polyvinyl chloride gaskets and epoxy-phenolic coatings for polyethylene/polypropylene gaskets.
Two-coat epoxy-free external systems consisting of white and transparent basecoats and clear varnish, designed for wet-on-wet application.
