Q: Why the electrostatic spraying of the middle coating coating and then electrostatic spraying of the top coat will appear on the top coat film thickness is very thin bad on the oil, the opponent of the middle coating can be a thicker top coat film is very good on the oil? Why the conductive ink will decrease a lot if the polyester resin is replaced by the chlorine vinegar resin?

 

A: These questions above relate to the conductivity of the paint ink coating. For example, the first question mark, after careful questioning of the customer, the hydrophilicity of the opponent in the middle coating coating to be good, drop of water in the middle coating coating, the opponent’s will be quickly moistened to spread, and the customer’s will beads of water, which indicates that the hydrophilicity of the coating the better the conductivity will be better.

The second question mark is PET conductive ink products, generally these conductive inks are used ternary chlorine acetate resin to do, conductivity are to meet the requirements, but then the industry halogen-free requirements to limit the use of chlorine acetate resin, changed to macromolecule linear polyester resins, the result is that the conductivity is greatly reduced. Why? One of the reasons is that chlorine vinegar resin structure contains chlorine and will be dechlorinated, from the polarity point of view and paint film residual inorganic acid, electrical conductivity are chlorine vinegar resin is much better than polyester resin. Then how to improve and enhance the polyester system of conductive ink conductivity has become a lot of customers and engineers urgently want to solve the problem, after a lot of tests to join the appropriate additives can largely improve the conductivity, the introduction of special additives added to the ink, add 0.5%, resistance value can be reduced by 5-10%, improve the conductivity of the ink.
