Drying: Appropriately dry the substrate to prevent the development of h2o places or surface defects inside the powder coating. Air drying, oven drying, or pressured air drying may be used, according to the substrate and facility’s abilities.
Steel: Metal substrates are usually pretreated with iron phosphate or zinc phosphate to reinforce adhesion and provide corrosion resistance.
Heat-delicate plastics and composite materials are frequently hydrophobic, have a reduced degree of wettability, and possess lower-Strength surfaces. These facets all negatively impact powder adhesion through the powder coating approach.
