Heat Resistant Coating

Operation method Remove contaminants -> Sanding -> 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. 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 Item Method Coating Thickness Curing Condition Remarks DY 850 Series Spray 10-25um 260°C x 5min   DY 10C Series 20-30um 160°C x 5min   DY 20C Series 15-25um 260°C x 5min   DY 30C Series 15-25um 380°C x 5min   Sintering When sintering DY 10C Series, DY 10C Series have each sintering temperatures as per product. sop, please refer to the manual. Progressively raise temperature and maintain the maximum temperature for 5 minutes. Suddenly heating can cause air bubbles, poor adhesion Cauton 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 5°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.
