Etch Primer - Marine Paint and Painting Equipment
Marine etch primer is a thin adhesion-promoting coating applied to aluminum, galvanized steel, and other difficult substrates before compatible marine paint systems. It improves coating adhesion and provides limited corrosion protection but is normally overcoated with a specified primer or finish.
ProShipWorks provides end-to-end support to source and supply Etch Primer for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.
