Can it be overcoated with cation?
A detailed explanation of whether topcoating can be done on cationic electrodeposition coating!
We often receive inquiries about whether it is possible to apply a topcoat over cationic electrodeposition paint. The answer is yes, it is possible and there are proven results. However, when a topcoat is applied over cationic paint, the adhesion is dominated by the cationic layer. If the brittle cationic coating cracks or peels, the topcoat may also tear, and in such cases, it will not be covered by warranty. Using a thin pre-coat film with salt damage resistance reduces the risk, but the adhesion will still be weaker compared to direct painting on aluminum or copper. Considering the costs, we recommend painting directly on aluminum or copper. *For more details, please refer to the PDF materials or feel free to contact us.*
