W8602-2001(basecoat)Two-layer water-base fluororesin non-stick coating

W8602-2001(basecoat)Two-layer water-base fluororesin non-stick coating
Product Detailed
a) Superior anti-corrosion property b) Safe and environment friendly c) Fine non-stick performance, easy to clean
Pre-treatment of substrate
This series of products are applied to aluminum substrates, such as thin aluminum plate, die-casting aluminum, etcFirst, degrease the surface, and then apply rubbing or sandblasting treatment to the surface with corundum(80# ~ 120#) to make the surface roughness in the range of Rat2.0μ ~ 3.0μ.The last step is to clean and dedust.
Preparation of coating
Fully disperse the coating by stirring or rolling on a ball grinder before operation.Stirring standard: Give a low-speed and uniform stirring (300 r/min ~ 900r/min) for 10 minutes, be sure there isno bubble.Rolling standard: Roll the coating for 40 minutes at the speed of 30r/min ~ 50r/min on the ball grinder.
 Viscosity adjustmen
The viscosity can be adjusted according to different spraying methods, dilute the coating with water if theviscosity is over high.
 Coating Filtration
Filtrate the coating with stainless steel or nylon filter net (100M ~ 150M) before using to get rid of impurities
Spraying of coating
 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.
 Spraying process
The spraying environment should be dry, well-ventilated, no smoking and fire.Air compressor should be degreased, dewatered and equipped with decantor before using.Adjust atomization and oil pump capacity of the spraying gun, make sure the workpiece is cleanand level.Basecoat spraying: Heat the substrate to about 350C before spraying basecoat.Basecoat film thickness: 15μm ~ 18μm; drying temperature: 120°C; drying time: l0min ~ 20min.Topcoat spraying: Spraying the topcoat after drying and cooling down the basecoat to normaltemperature;Topcoat film thickness: 8μm ~ 12μm; drying temperature: 120°C ~ 150°C; drying time: l0min ~ 15min.
 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.
 Cool down the workpiece
Water cooling, natural cooling and air cooling are all available.
 Storage of coating
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. The shelf life of the coating is 6 months.
