Two colors have been added to the PPG Delfleet Essential commercial paint system. The low VOC epoxy primer is available in white (No. ESU481) and black (No. ESU482) in addition to the company's traditional gray primer. Each is compatible with Delfleet Essential basecoats and single-stage topcoats. The primers, with strong adhesion and corrosion-resistance qualities, are flexible and suitable for use with a broad range of substrates, including aluminum, cold rolled steel, stainless steel, galvanized steel, galvaneal, fiber glass and enamel surfaces. The thin film epoxy primers lay down easily with no sanding required. Both offer fast recoat time and quick-drying capability that calls for as little as 30 minutes before topcoating. They can be applied in a 4:1 mix ratio and have a four-hour potlife.
