Adhesion over Powder Coated Surfaces
Is there a way to improve adhesion of two-component polyurethane adhesives to polyester- and epoxy-based powder-coated surfaces?
Q. Is there a way to improve adhesion of two-component polyurethane adhesives to polyester- and epoxy-based powder-coated surfaces? K.P.
A. It is possible to apply an adhesive over a powder. The challenge is to find an adhesive/powder combination that works. You need to select a powder that meets the performance and appearance properties you need, and then work with an adhesive supplier to find the correct adhesive. Polyester powder is more likely to provide adhesion than epoxy powder. You can roughen the surface where you need the adhesion, but that may not be feasible. Talk to an adhesive supplier and you should be able to make it work.
