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
the storage period can be re inspection, if the results meet the requirements, can still be
used.
Health and safety: the powder coating is a non-toxic product, but in the use of the
process should avoid the inhalation of dust. Suggested that the operator wear suitable dust
masks, glasses. If possible, try to avoid long-term contact with the skin and powder
