Product introduction:
This type polyethylene powder coating is polyethylene resin as the base material, adding anti-aging agent, glue, pigments and other modified thermoplastic powder coating, with excellent adhesion and corrosion resistance, with polyethylene itself has Good chemical stability, electrical insulation, low temperature resistance.
Application areas:
Applicable to all kinds of special refrigerator shelves,exterior fence,fire equipment, civilian tools and other anti-corrosion coating.
Physical properties:
Nonvolatile content: ≥99.5%
Dry flow: fluidized floating ≥ 20%
Weight: 0.91-0.95 (varies by color)
Particle size: 120-300 microns
Melt index: 5-50 g / 10 min
Chemical property:Acid and alkali resistant, insoluble in water.
Packaging: composite paper bag packaging, net weight 20 kg per bag or 25 kg per bag
Storage: Avoid near fire, in less than 40 ℃, ventilated, dry room, storage period 1 years.After one year by re-testing, if qualified, can still be used.
Application Note:
1. Surface treatment: according to the substrate and the required performance of the treatment, after treatment the substrate surface should be neutral;
2. Workpiece dipping temperature: 260-420 ° C (adjust the temperature according to the size of the workpiece heat and room temperature, appropriate preheating conditions are determined in order to get a smooth coating, while it is required to prevent the film at high temperature heat aging);
3. Using dip coating or fill the air suction coating method to paint,after removal of the workpiece by 180－230℃/0－5min(According to the size of the workpiece heat capacity and powder melt flow index to adjust) ,plastic leveling, air-cooled or natural cooling to the room temperature.
