The Problem-Solution Series: Part 17
Poor Chemical Resistance Problem: The film of your powder-coated part has poor resistance to chemicals. How can you stop this from happening again? Origin/Cause: This lack of resistance could be a result of either unsatisfactory cleaning, poor pretreatment, or a mixture of both. Solution: Assess the conditions and the chemicals of the cleaning, rinse, and pretreatment stages. Second Origin: It is also possible that a change has been made in the substrate but not to the process. Solution: Contact substrate suppliers to find out if any changes to the substrate have been made. Third Origin: Under-cured films will usually exhibit low adhesion. Solution: Modify the cure conditions by increasing both the temperature and dwell. For additional information on powder coatings, visit our website at tcipowder.com .
