Plant and working procedures

Preparation process

Powder coating is a coating which is applied on the job in a powder form, it does not require any liquid carrier while the paint can be applied on a job in a liquid form only and requires the liquid carrier which causes the dropping sag, run and storage problem etc. It is a dry paint, which gives almost 100% finish maximum material use with no wastage in over spray, spillage etc.

Pre Inspection

The job is inspected for fit and finish to ensure all components are fitted to final product.

Degreasing Bath

The product is submerged for 20 minutes in a degreasing solution at a temperature of 60 Degree Celsius. This removes all grease and oils. Then the product is rinsed in a clean water tank to remove excess chemicals.

Descaling Bath

The product is submerged for 30 minutes in a Acid solution at a temperature of 50 Degree Celsius. This removes all the scale from the steel. Then the product is rinsed in a clean water tank to remove excess chemicals.

Zinc Phosphate Bath

The product is submerged for 15 minutes in a Zinc Phosphate solution at a temperature of 60 Degree Celsius. This adds a fine corrosion resistant coating. Then the product is rinsed in a clean water tank to remove excess chemicals.

Sealant Bath

The product is submerged for 10 minutes in a sealing solution at a temperature of 50 Degree Celsius. This adds a final coat to seal the product and allows for better adhesion when applying the powder.
