The Viking Yacht Company’s Powder Coating Process
Marine powder coating is the most effective way to safe-guard boat parts and fixtures from the high-risk of saltwater corrosion. The basic elements of air, water, salt and the sun's powerful rays are all tremendously corrosive to metals in any marine environment and combining them all is a surefire recipe for deterioration. Using the powder coating paint process will protect your aluminum, stainless steel, and other metal boat parts with the utmost durable finish.
The strength of a powder coated metal finish will protect your boat and marine fixtures in all kinds of weather conditions and climates. Another excellent feature of powder coated surfaces is their ease of maintenance. By powder coating any marine brass work or copper fittings means, you can preserve the shine and luster of your boat's metals for much longer without the hassle of buffing and polishing. In addition to preserving your metal finishings, powder coating can also be used as a method for coloring rails and matching other boat parts in desired hues.
The Viking Yacht Company recently released a video as part of their “How We Do It” mini-series which details their powder coating process.
Once raw materials like aluminum or steel are received, they must be sanded for a smooth finish. The powder coating process at Viking Yachts begins with placing the metal components in a series of chemical baths to ensure debris and contaminants are washed away. The pieces will sit in each chemical solution for a set amount of time to ensure maximum effectiveness. The various steps in the chemical bathing process are phosphoric acid, water rinse, iron phosphate, water rinse, chromate, water rinse and a final water rinse. Once dry, components are hung from tracks grounded in the factory ceiling. This method of hanging allow for better overall powder coverage and necessary for the bonding process. Next, statically charged powdered polyester material is sprayed through a diffuser onto each piece of metal. The powder adheres to each part by an electrostatic bond. Parts are then place into an oven to finish the coating process. The end result is a sleek, good looking and well-protected marine metal component.
