(1) The surface state of the impregnated workpiece, the corrosion of the workpiece after dipping is poor, the surface treatment of the workpiece, the bonding force is better, the galvanized part after dipping is the worst, and the galvanized part often needs to be primed or sandblasted before dipping.
(2) The quality of powder coating. In order to improve the binding force of the coating film, an adhesive should be added when configuring the powder coating to improve the binding force.
(3) Dipping temperature. Under normal circumstances, increasing the dipping temperature can appropriately enhance the bonding force between the paint and the workpiece.
