The dip coating process typically includes several key steps:
1. Immersion: The substrate is dipped into the coating solution. 2. Dwell Time: The substrate remains in the solution for a specific period to ensure proper interaction between the substrate and the coating material. 3. Withdrawal: The substrate is slowly pulled out of the solution at a controlled rate. The withdrawal speed significantly influences the coating's thickness. 4. Drying/Curing: The coated substrate is allowed to dry or is cured using heat or light, depending on the material.
