PTFE Water Base Coating

Features We have various PTFE Water Base coatings according to the color and physical property and we are making a constant effort to develop coating materials based on the demand of customer. Operation method Remove contaminants -> Drying -> Sanding -> Primer Coating -> Sintering -> Mid Coating(In case of 3 Coating type) -> Top Coating -> Sintering -> Cooling Application method Remove contaminants : Surfaces must be clean and dry otherwise, They cause a rough surface, poor adhesion and pin holes of coating. Sanding : The surface should be treated with sandblasting, liquid honing, or an equally effective process. When sandblasting, a 80~100 mesh sand powder should be used for the iron or stainless steel base materials. Coating : Coating preparation Firmly seal the container, slowly rotate the container at an angle ten times by hand, and then mix the solution with a rotating mixer until it is evenly dispersed. Do not open containers until ready to use. Keep lid on container when not in use. Filter the solution with a 100-200 mesh stainless steel screen after rotating enough times. Spray nozzle : 0.8-1.3mm, spray pressure : 1.5-2.5kg/m3 Recommended distance between the spray gun and the substrate : 15-25cm 2 Coating system Item Method Coating Thickness Curing Condition Remarks Primer Spray 10~15um 150°C x 5min   Top 10~15um 380°C x 5min   3 Coating system Item Method Coating Thickness Curing Condition Remarks Primer Spray 10~15um 150°C x 5min   Mid 10~15um 380°C x 5min Wet on wet Top 5~10um Sintering When sintering primer, temperature is 110°C ~ 180°C according to the coating. In case of same product, As the sintering temperature is higher, quality of coating become better. Progressively raise temperature and maintain the maximum temperature for 5 minutes. Suddenly heating can cause air bubbles, poor adhesion Caution White spots may appear on the surface of the substrate when the substrate and coating is cold, especially in winter time because of a problem in coating flow. To avoid this phenomenon, please keep it warm(over 10°C) and pre-heat it before working. Keep adequate ventilation during application Don't mix other types of paint. especially, separate from Powder Coating. Ideal storage temperature is 5°C ~ 30°C in warehouse.
