Directions for Use
 
Process
Purpose
Recommendation
Surface Preparation
Degreasing
To remove oil and dust from the substrate
Alkaline degreasers.
Pretreatment For Aluminium Chromating
To improve anti-corrosive performance and adhesion of paint film to Aluminium substrates
Suitable chromate conversion coating
For Steel Phosphating

To improve anti- corrosive performance and adhesion of paint film to steel substrates

Passivated Zinc phosphate
(Coating wt.1.5-2.5 gms/ Sg.M.)

 
Note: Process to be followed as per chemical manufacturer's recommendations.
 
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 earthing. 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.

 
Storage & Packing
Storage

Store in closed, cool room (below 30°C) in dry condition and in the original packing.
Exposure to direct sunlight, heat and high humidity should be avoided.

For best results, the stack height 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.
 
Packing
Standard pack size is 10 & 20 kgs
Clear Powder's pack size is 7 kg
