Notes: 
1.The above tests used 0.8mm thick cold-rolled steel plates with a coating thickness of 50-70 microns.
2.The performance indexes of the above coatings may vary with different powder varieties.

Average coverage area: 
10-12 sq.m./kg; film thickness 60 microns (calculated with 100% powder coating utilization rate) 

Packing and transportation:
cartons are lined with polyethylene bags, net weight is 20kg. Non-hazardous materials can be transported in various ways, but only to avoid direct sunlight, moisture and heat, and avoid contact with chemical substances.

Storage condition: 
Store in a ventilated, dry and clean room at 30℃, not close to the fire source, central heating and avoid direct sunlight. It is strictly prohibited to pile up in the open.
