CORTEC® CORP.: VpCI™-373 is a low-VOC water-based wash primer designed to promote adhesion on aluminum, stainless and galvanized metals and to eliminate previously required hexavalent chromate or acidic washes. Based on the company's Advanced Green Technology, the primer is available in clear or green tint and reportedly requires less than half the thickness of other coatings. It is suitable for stand-alone protection of indoor/sheltered environments or can be topcoated with the company's VpCI™-386 for outdoor exposure applications. Call 800.426.7832 or visit
