Introduction to dielectric pastes layer suitable for metal substrates of thick film heater
At present, there are few thick film pastes suitable for metal substrates.
It is worth noting that the surface of the steel plate must be kept clean and dry before the printing medium layer, and the corrosion of the steel plate by degreasing solvents or detergents should be as small as possible. After removing oil, the steel plate should avoid contamination, especially do not leave finger marks, because these will corrode the steel plate in the subsequent heating process. In addition, depending on the process requirements, the surface of the steel plate can be suitably roughened to improve the bonding strength of the medium layer and the steel plate.
