Many solvent-based anti-corrosive paints and anti-rust oils have drying requirements in addition to coating,otherwise anti-corrosive paints or anti-rust oils cannot adhere. Waterborne anti-rust paint is not the case.Because water-based paint is water-based,it can be successfully attached to a wet surface,eliminating the need for drying. This is an advantage of water-based anti-rust paint.

How to deal with the surface of water-based anti-rust paint before painting
As the saying goes, "seven-point paint three-point paint." The correct handling of the substrate can have a major impact on the performance of the coating. Waterborne anti-corrosive paint is no exception.
During the processing, transportation and storage of the workpiece, the surface often has the molding sand, the slag dust and the oil and other contaminants left by the oxide scale and the rust mold.In order to make the deep layer firmly adhere to the surface of the workpiece, the surface of the workpiece must be cleaned before painting. Otherwise, it not only affects the bonding strength and corrosion resistance of the coating with the base metal, but also makes the base metal even Corrosion can also continue under the protection of the coating, causing the coating to peel off, affecting the mechanical properties and service life of the workpiece.Therefore, the surface treatment before the painting of the workpiece is an important guarantee and measure for obtaining a good quality protective layer and prolonging the service life of the product.
In order to provide a good surface of the workpiece, the surface of the workpiece is treated before painting:
1.No oil
2. No rust and oxide
3. No adhesion impurities
4. No residue such as acid and alkali
5. The surface of the workpiece has a certain roughness
