Requirements for phosphating before painting
Thread Content
Question: Are there any special requirements for phosphating before painting?
The pickling process must be thorough to remove all the oxide scale from the surface; the phosphating layer should be even, and drying must be complete. Keep it clean~ That’s about it, I guess:lol
There are no special requirements; since phosphating is to be carried out, it is necessary to design the type and thickness of the phosphating film based on specific substrates, specific products, and specific applications. In addition, the resulting phosphating film must be dense, uniform, and dry, remaining clean and unaltered before proceeding to the next processing step.
Surface degreasing, dehydration, and rust removal must be thorough
