Can water-based paint be used on transformers?

No problem at all. If you want to find the right product, come to me. At present, there are many merchants of water-based insulating paint, but most of them fail to solve the problems of voltage resistance, tin plating and pin foaming of electronic transformers. If you find the right product, this series of problems is not a problem. Waterborne insulating paint can completely replace solvent-based insulating paint in motor, power electronic transformer and coil.
