Metal coatings are used to provide a layer that modifies the surface properties of metal for corrosion resistance and improved paint adhesion. Vanchem provides metal coatings for hot and cold rolled steel, galvanized steel, aluminum (cast and plate), and stainless steel.
Some of the different types of metal coatings include:
Metal coatings are applied by spray, immersion, and manual rub-on. Spray washers provide continuous chemical impingement to the metal surface and is the most popular form of metal coatings pretreatment. Immersion systems are utilized where multi-stage pretreatment is required. Spray washers occupy a large footprint in the plant while immersion systems do not. Many modern immersion systems are now automated wherein the past they were mostly manual. Manual rub-on metal coatings is the least popular method of metal finishing and mostly applies to spot repair.
Vanchem has a full line of spray metal coatings, cleaners, iron and zinc phosphate, non-chrome sealers, rust inhibitors, de-scaling, and an assortment of specialty additives. We also carry a full line of metal cleaners, iron and zinc phosphates, non-chrome sealers, inhibitors, and so forth. See Pretreatment in our product guide for more information.
The metal finishing process of metal coatings for typical spray application systems is applied using a 3, 5, or 7-step operation, depending on the type of metal, the surface condition, and the paint adhesion performance requirements of the customer. With immersion systems, normally multiple stages of coatings pretreatment is dictated by the performance requirements of the customer.
