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, and there are successful cases. However, when a topcoat is applied over cationic paint, the adhesion is dominated by the cationic layer, which is prone to cracking. If the cationic coating cracks or peels, the topcoat may also tear, and in this case, 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 painting directly 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.*
