What are the causes of the "painting mark" on the surface of the electrophoretic paint film
What are the causes of the "painting spots" on the surface of the electrophoretic paint film? How to prevent it?
Due to the contamination of the substrate surface or the phosphate film, streaks or map-like marks can still be seen on the surface of the dry paint film after the electrophoretic paint is applied.
It differs from water-drop marks and paint-mark marks in that the coating surface is still flat, but it has an influence on the water and corrosion resistance of the coating film.
