Applied by electrostatic spraying gun that can provide negative tension of 60-80 kV.
Curing schedule : 180-200℃ /10-15 minutes depending on the powder chemistry.
Optimal film thickness : 80 -110 um The size of antique vein obtained depends on the coating thickness.
Excessively thin or thick films will not give a satisfactory finish.
GLOSS AND COLOR RANGE
Various combinations of base and vein pattern colors are possible. High gloss is usually recommended .
SUBSTRATES AND PRE-TREATMENT

Should be stored under dry conditions with good ventilation at a temperature not exceeding 30 C. Storage period recommended should not exceed 6 months,in case exceeding 6 months without affecting their free flowing properties, the powder will still have optimal characteristics.
Should be protected from excessive heat,humidity,water and contamination with foreign materials such as powder, dust, dirt, etc.
Any leftover powder should be kept in an appropriate area that is cool and dry. Do not expose to the air too long as the powder properties may deteriorate with the moisture.
