Average coating rate ofEpoxy polyester powder coating
Under the condition of 100% powder utilization and 80 μ m film thickness, the coating rate is 9-12 m2 / kg.
Storage conditions of Easy-maintainable Epoxy Polyester Powder Coating
Epoxy polyester powder coating should be stored in a ventilated, dry and clean room with temperature lower than 25 ℃.
Epoxy polyester powder coating should not be close to the fire source and heating. It should avoid direct sunlight. It is strictly forbidden to stack in the open air. Under these conditions, the powder can be stored stably for 12 months. If the storage period exceeds, it can be inspected again. If the results meet the requirements, it can still be used.
