EPP314 Epoxy Sealer/Tie Coat/Bonding Coat belongs to Epoxy. Suitable as a primer or sealer for galvanized steel structures, also for thermally sprayed zinc metal surfaces, and as a tie coat applied over surfaces already coated with zinc-rich primer to seal porosity, prevent blistering, reduce zinc salts and enhance adhesion. High performance, two-component, grey or iron red. Parameters on this page: dry film thickness 20–40 µm, theoretical spreading rate 21 m²/kg, number of components two-component.
