| Application
Recommendations |
|

|
|
Application Voltage - 60-90 KV
Stoving Schedule - 180° C (Effective metal temperature)
for 10 to 15 minutes
It is essential that the compressed air is completely
filtered to avoid contamination by oil, dust or water.
Jigs should be clean in order to maintain good ear thing.
To avoid contamination, when using different colors,
through cleaning of the application and recovery systems
must be carried out between each color. Care should
be taken in keeping different colors and types of powders
well segregated.
The total curing time of the film is dependent on several
factors like material substrate thickness & mass
of the material and shape of the material.
The effective curing time commences when the objects
has reached the recommended temperature.

should not exceed three cartons |
|
Partly used bags must be tightly
closed after each removal and stored carefully inside
the carton in a cool dry storage room. |
|
For best performance use within
six months. |
