Prep/Pretreatment
1.Remove all coatings, oils, and contaminants from the substrate with either a chemical stripper (B17, Rim-Strip, Jem-Strip 427) or a degreasing agent
(Brake Parts Cleaner, or Simple Green);these are some examples of chemical strippers and degreasers that work well depending on the condition of the substrate.
2.Plug/mask off any areas that you do not want to be coated. Improper masking on certain mechanical parts or mating surfaces may cause tolerance on functionality issues.
3.A sand-blasted profile is highly recommended for the substrate to remove any rust, scale, or other coatings. This is also a crucial step to ensure maximum coating adhesion. For best results, blast at 80 - 100PSI using a 100-mesh dry grit material such as aluminum oxide or garnet sand.
4.Fixture part(s) to allow for the best view and application access; this can be done by using support hooks and support wires. Makke sure to place part(s) in such a way that they will not bump into each other. Ensure the part(s) being hung have a clean metal-to-metal contact point with thehooks, rack, and the part(s) themselves. This is imperative to complete aproper earth-ground connection via cold electrostatic spray application.
5.Blow off the substrate with a high-pressure air nozzle to remove any
sandblasting media/dust left on the surface. Work in a well-ventilated area and always wear proper Personal Protective Equipment (PPE), e.g., safety goggles and respirator.
6.We recommend but do not require, that parts are placed in an oven at 450°F (232°C) for approximately 30 minutes. This will aid in discharging part(s) that have developed any static charge and evaporate any surface moisture or solvents from degreasing. If contaminates are drawn to the surface during this phase, the affected areas will need to be addressed.
