Metal Coatings

Vanchem can supply you with high quality metal coatings

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:

  • Chemical treatment of aluminum
  • Chromate conversion coating
  • Conversion coatings
  • Zinc phosphate
  • Low Temperature Surface Treatment
  • Finishing Aluminum Castings

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. For more detail, see our technical article metal surface treatment.

Vanchem is highly driven to meet the highest quality standards in formulating metal coatings for industry. For more information, contact us at our corporate headquarters in Burlington, Ontario.
