i) Spraying method
Compressed air spraying is available. All general spray guns (pressure feed type, gravity feed typeand siphon type) could be used. The caliber of spray nozzle is Ø0.8mm ~ 1.5mm, the spray headpressure is 1.50kgf/cm² ~ 4.0kgf/cm². The spray gun should keep a certain distance fromworkpiece in accordance with the spraying environment and coating properties.
ii) Spraying process
The spraying environment should be dry, well-ventilated, no smoking and fire.Air compressor should be degreased, dewatered and equipped with decantor beforeusing.Adjust atomization and oil pump capacity of the spraying gun, make sure theworkpiece is clean and level.Basecoat spraying: Heat the substrate to about 35°C before spraying basecoat.Basecoat film thickness: 15μm ~ 18μm; drying temperature: 120°C; drying time:l0min ~ 20min.Midcoat spraying: Spray midcoat after drying and cooling down the basecoat tonormal temperature.Midcoat film thickness: 20μm ~ 30μm.Topcoat spraying: Spray the topcoat directly after spraying the midcoat.Topcoat film thickness: 10μm ~ 12μm; drying temperature: 120°C ~ 150°C; drying time:l0min ~ 20min.
iii) Film curing
Set temperature within the drying oven (or tunnel drier) at 120°C ~ 150°C. Keep the sprayedworkpiece in for l0min ~ 15min, then slowly increase the temperature to 380°C ~ 400°C and keepfor another 5min ~ l0min.Please kindly note that both higher beginning temperature and rapid temperature increasingcould lead to blister of film.Besides, drying oven (or tunnel drier) should be well-ventilated, otherwise, the discolorationwill occur.Adjust the holding time according to the size of substrate and heat-transfer ability of the materialduring curing or sintering process.
iv) Cool down the workpiece
Water cooling, natural cooling and air cooling are all available.
 Storage of coating
i. The storage place should be dry and well-ventilated. Avoid direct sun exposure,and keep away from the source of ignition and heat. The storage temperature should be between 10°C ~ 30°C . Have a weekly shake on the ball grinder ( 30rpm ~ 50rpm * 15min ~ 30min ). Never make it freeze in winter. ii. The shelf life of the coating is 6 months.
