Color of CED paint  

June 12, 2008

Why generally OEM instries using Black or Grey CED paint? If we are using red or blue CED paint then what kind of problem create in regular painting process?

Absolutely no problem if you develope the CED paint color may be blue or red with your Paint supplier. How ever there are seperate stages for CED , UF1 , UF2 & DM rinse stages are required.

You can do a Epoxy Grey ED followed by UF rinses then Acrylic top coat ED and rinses.

CED coating and its development has been intertwined with the automotive component surface finishing requirement. The requirement here has been a primer coating in black or gray. And only for this reason, in India particularly, only these two colours are available. Outside India, where there is sufficient demand CED coating is also available in different colors.
There is a second facet to this. The epoxy based CED coatings have a high SST resistance. But they do not have UV resistance. To make it UV resistant, CED coating is used as a primer coating followed by Acrylic or PU topcoat as written by my friend Saravanan. This gives the component the best of both the worlds.
There are single coat Acrylic Ecoatings also available in colour. But again not in India. Then there are clear coat Ecoats which can be tinted. These are available in India. But for each coating or combination of coating the performance will change. You will have to evaluate what you require and the coating or combination of coatings can deliver.
