Corrocoat Benelux has recently completed a contract for a leading automotive manufacturing company to clean and protect the internal surfaces of an electro-deposition (ED) coating tank to extend its working life.
Using a combination of dip and spray, ED coating plants are used throughout the automotive industry. In these plants, electrically charged paint pigments reach every corner of even the most complex fabrication. Un-deposited material is then washed away and after stoving the final coating becomes hard and durable.
The tank must be kept in a very clean condition, free from anything that could affect the quality of the finished component. After submitting a highly competitive tender, Corrocoat Benelux was contracted to carry out the tank cleaning and coating using Corrocoat materials approved by leading ED coating suppliers.
This involved blast cleaning all surfaces to standard SA 2 ½ before applying Polyglass PPA primer, followed by two coats of Polyglass VEF. Once cured the coating thickness was spark tested to ensure a pin-hole free minimum thickness of 1500 µm before a topcoat of VE Veilcoat applied.
As with many automotive production plants, disruption to production had to be kept to a minimum so the work was scheduled to be completed in a planned outage.
