with 0.8 mm thick rust and oil removal cold-rolled steel plate, the film thickness is 50-70 

microns.

2 the performance index of the coating film may change with the change of color and 

luster.

Average coverage: 9-12 square meters / kg, film thickness of 60 microns (to 100% of 

the powder coating usage)

Packaging: carton packaging, lined with two layers of polyethylene 

bags, 20 kg net weight per box.

Storage requirements: stored below 35 degrees Celsius, 

ventilation, dry, clean room, not close to the fire, heating, avoid direct sunlight, no 

open pit. Under the above conditions, the powder can be stored stably for 12 months. Over
