3 Stage On-line Pre-Treatment

Prior to Powder Coating all components pass through our three stage, on-line pre-treatment process plant.  This process helps provide the product with increased shelf life and low maintenance, plus zinc chromate protection. All components are loaded onto an automated conveyor and follow the stages listed below:

Stage One
Each product is treated with chemical degreasing agents that remove any oils or surface contaminations.

Stage Two
The components continue through a clean water rinse to wash and remove the chemical from the product.

Stage Three
Optional (CF20) protection is available. This is ideal for aluminium parts that require further corrosive protection. (Up to 1000 hours salt spray test has been proven). This would depend on the environment, giving approximately 10-15 years life expectancy
