the influence of product material and structure on coating
2025-05-19
According to relevant information, the coating thickness is generally more than three times the surface roughness value of the product material in order to achieve good corrosion resistance.
For example:
The salt spray corrosion resistance of the 40 µ m thick low-temperature baked water-based chassis paint film can reach over 300 hours on phosphated cold-rolled plates, over 240 hours on hot-rolled plates, and only about 150 hours on cast iron plates.
The salt spray corrosion resistance of 20 µ m thick cathodic electrophoretic paint can reach over 1000 hours on phosphated cold-rolled plates, over 800 hours on acid washed and rust removed hot-rolled plates, and only about 600 hours on shot blasted and rust removed hot-rolled plates.
