CORTEC® VPCI™-373 WASH PRIMER ELIMINATES CHROMATE & ACID TREATMENTS FOR ALUMINUM, STAINLESS AND GALVANIZED

Chemists from Cortec Laboratories have introduced VpCI™-373, a low-VOC water-based wash primer specifically designed to promote adhesion on aluminum, stainless and galvanized metals, and to eliminate previously required hexavalent chromate or acidic washes.  Rather than going through the time consuming, costly and environmentally damaging process of using acids, manufacturers can simply apply a thin coat of VpCI-373 and then paint as usual. The end result is improved adhesion, more durable corrosion protection, lower environmental and worker safety impact.

Originally developed to meet the stringent requirements of RoHS regulations in Europe and the requirements of aircraft manufacturers, VpCI-373 offers an easy-to-implement alternative to chromate or acid washes, while increasing performance, durability and corrosion of metals. Utilizing Advanced Green Technology from Cortec Corporation, VpCI-373 is available in clear or green-tint, and requires less than half the thickness of other coatings, offering drastic cost savings. In addition, VpCI-373 does not contain hexavalent chromium that is commonly used as a surface treatment prior to painting; hexavalent chromium restricted and monitored by RoHS in relation to electronics manufacturers.

By incorporating Cortec’s proprietary Vapour phase Corrosion Inhibitors (VpCI™) chemistry, VpCI-373 provides unparalleled corrosion protection, and virtually eliminates blistering, creepage and adhesion problems. VpCI-373 is suitable for stand-alone protection of aluminum, stainless and galvanized metals for indoor/sheltered environments, or can be top-coated with Cortec VpCI-386 for outdoor exposure applications.
