show up only after full cure, storage, or service exposure, when adhesion, flexibility, or weatherability becomes the limiting factor.<\/p>\n<p><strong>Should coating additives be chosen one by one outside the full formula?<\/strong><br \/>It is usually safer to screen them inside the real formula because resin choice, pigments, and the rest of the additive package can change the result.<\/p>\n<p><!-- lc-commercial-end --><\/p>","protected":false},"excerpt":{"rendered":"<p>Vapor phase cleaning, the workpiece is washed, rinsed and dried in the solvent vapor layer, and the
