Why Pretreat for Powder Coatings?
Any given metallic surface has a layer of dirt, oil, mill scale, etc. that must be cleaned and removed prior to powder coating. A coating will not adhere well to a contaminated surface and will result in poor performance, thus making proper pretreatment necessary.
There are a variety of methods that will clean and remove soils from metals. The pretreatment method used is determined by the part to be coated (size, configuration, material), the type of soil to be removed (dust, wax, oil, etc.), and the performance requirements of the finished product.

Pretreatment is the base for powder coating. The highest quality powder coating will show you excellent results ONLY if the pretreatment is done correctly, maximizing the benefits of powder coating. The results of improper pretreatment include appearance of oily patches, pin holes, rust patches, reduced resistance to weather, and overall poor powder coating performance.
