Abstracts: A study using an experimental design of dispersion coating with PTFE ambient cured process is presented. The effects of five major process parameters of the coating, i.e. polymer concentration, dip coating time, presence of immersion rinsing, spray rinsing, and air blow drying on surface residue defect, coating thickness, and wear resistance were investigated. The study was conducted starting with two level factorial experiments to identify the most significant parameters in the coating process and concluding with response surface methodologies to establish an optimum operating condition for the coating in anodizing aluminum process. With the key parameters, an operating process condition for the dispersion coating with PTFE that provided elimination of residue defects.
