MSC Walbridge Coatings

Products

• Zinc Plated
Electrogalvanizing uses electricity to deposit zinc onto sheet steel, making it corrosion resistant. The EG surface is very formable, flexible, weldable and uniform, making a good fit in many applications. Walbridge Coatings has the ability to apply zinc at coating weights from 10 - 90 g/m² per side, as well as differential and one-sided coatings.

• Zinc-Nickel Plated
Environmentally safe zinc-nickel alloy plating has a corrosion protection more than five times that of conventional zinc plating. Zinc-nickel coatings provide a harder surface than zinc EG making it a more scratch and wear resistant surface. Walbridge Coatings can coat from 10 - 40 g/m² per side of zinc-nickel, as well as differential coatings. The surface is formable, flexible, weldable and paintable similar to the zinc EG.

• Organically Coated Zinc or Zinc-Nickel
This coating was originally designed specifically for gas and alternate fuel tanks, but it is finding a place in applications where chemical resistance is a necessity. An added plus to this multi-layered coating is its corrosion resistance.

The coating is a combination of a chrome seal, metallic filled epoxy paint and a soap based dry film lubricant that aids in stamping.

• Conventional Zinc Phosphate
Conventional Zinc Phosphate + Chrome Sealer
Typical phosphate coating weight: 200 - 300 mg/ft² applied by the conventional immersion process and the chrome sealer by the conventional immersion or spray process. The chrome sealer can also be applied by the Roll Coat process with a typical coating weight of 0.5 - 1.0 mg/ft². This product provides an excellent base for organic coatings with some additional corrosion protection alone.

• Dried-in-Place Phosphate (DIPP)
Typical coating weight: 0.5 - 1.5 mg/ft² applied by the Roll Coat technique that produces a non-crystalline deposit that is not visible even at high magnifications with a scanning electron microscope. Whien DIPP is oiled with standard rust preventative oils, the formability of zinc is greatly enhanced. After forming, the oil and be removed with a conventional cleaner leaving the phosphate film intact. The DIPP film can be treated further with a conventional phosphate to provide a base for paints. As the coating is developed currently, it will not provide the same paint base properties as conventional phosphate. The DIPP product can be welded, but there may be degradation in the number of spot welds achieved before weld tips must be dressed.

• Dry Film Lubricants
Acrylic Based Dry Film Lubricant
Typical coating weight: 200-250 mg/ft² applied by the Roll Coat technique. This product greatly enhances the formability of the zinc coated sheet steel. This product is weldable. The acrylic coating is removed with a conventional hot caustic cleaner. This product is shipped dry and provides some corrosion protection.

• WalCoat ^TM AF
Electrogalvanized cold rolled steel with a thin layer of organic coating applied. This product is fingerprint resistant and has excellent corrosion resistance for indoor applications. The organic coating contains an acrylic polymer that resists the oils and moisture that are transferred during handling. Product can also be applied over a zinc nickel product. Typical coating weights of 1 - 2 mg/ft² of chrome and 75 - 150 mg/ft² dry film.

• 72" Metal to Metal Laminate
Multilayer composites of various core materials are placed among layers of sheet metal, and are manufactured in a continuous roll-to-roll process. Reduces noise from vibration and creates thermal barriers. Proprietary technology capabilities meet specific user requirements.
