Electrostatic blue Polyester wrinkle Powder coating

Applications

• Applied by electrostatic spraying gun that can provide negative tension of 60-80 kV.

• Curing schedule : 180-200ºC /10-15 minutes depending on the powder chemistry.

• Optimal film thickness : 80 -110 um.

• The size of wrinkle pattern obtained depends on the coating thickness.

• Excessively thin or thick films will not give a satisfactory finish.

Average Coverage

7-10m³/kg, the membrane is 60μm

(calculate by 100% utilization rate of powder coating).

Storage Requirements

Store below 30 °C, ventilated, dry, clean room, not near the fire, heat, direct sunlight, open dumps is prohibited.Under this condition, the powder can be stable for 12 months, more than the storage period may be re-examined, such as the results meet the requirements, can still be used.
