It is water based coating method done on metal components. Coating is done by keeping the component connected to a circuit as the cathode and positively charged paint particles (anode) suspended in aqueous medium are deposited under direct current. Deposited film does not re-dissolve and the un-deposited material is rinsed off.
Salient Features:
Extremely high corrosion resistance, a 20 micron dry film thickness can withstand as much as 1000 hourssalt spray test ASTM B117
Able to coat highly recessed areas
Able to coat complex shapes with a very high degree of accuracy and repeatability
Freshly deposited film is insoluble in water, permitting complete rinsing and recovery of dragged out material.
Uncured paint is dry enough to allow careful handling
Unlike Spray Coatings, CED Paint does not wash off in enclosed areas due to hot Vapours
Simple process - eliminates dependence on skilled manpower. Fully automatic PLC based plant
The deposited film is reproducible from part and from day to day
