Electrostatic Powder coating is the technique of applying a dry paint to a part. This is normally done by a spray gun and an electrostatic charge applied to the part. The part is then placed in an oven and the power particles melt and coalesce to adhere to the part as a film.
The benefits of powder paint is that because of the electrostatic charge of the paint there is a very effective coverage of the part even into cracks and bends where a wet paint might not reach. Powder paint is a tough, abrasion resistant finish which is great for outdoor use. Short Run Pro has its own powder paint capabilities.
Short Run Pro utilizes the highest quality wet paint systems for total coverage of brackets and parts. All parts we cleaned and a tough industrial primer is added to the part. The highest grade paints (considered automotive grade quality) are then spray painted onto the part over the dried primer. The result is a tough durable finish that will last.
Zinc plating involves the electrolytic application of zinc by immersing clean steel parts in a zinc salt solution and applying an electric current. This process applies a layer of pure zinc that ranges from a few microns on cheap hardware components to 15 microns.The finish of this type coating is normally a shiny silver finish. Due To the nature of this process a consistent finish is not always achieved and this type finish would not be considered decorative but effective in resisiting rust. The Zinc deposits on the metal acts as a barrier to oxidation (rust).
Black oxide is a conversion coating formed by a chemical reaction. The reaction between steel and hot oxide bath results in a magnitite coating being formed on the part. The part surface is normally a dark to matte black color after the process. The finish would not be considered decorative but adds an antique or flat black type look. The finish will not flake and is durable. The process also provides improved lubrication to the part to resist galling. It does not exhibit "white rust" so it is excellent for elecrical cabinet brackets.
