We offer Primer For Plastisol. If good adhesion to plastisol is required, the parts should be primed prior to coating with vinyl plastisols. Primers are a combination of resins in solution in solvents, or water. Introduction of foreign material, into the primer, will eventually destroy its adhesive characteristics. Primer will give a good adhesion to most types of vinyl plastisols to most types of metal. For optimum adhesion, the primer-coated metal should be pre-baked at oven conditions that will bring the primer coat and adjacent metal surface to 191ºC for five (5) minutes or longer. However, if the part is exposed to moisture for a length of time, the adhesion may be lost. Optimum adhesion is obtained on clean metal surfaces that are free of rust,grease, dirt, scale, etc. Sand blasting or acid etching generally give excellent adhesion because they remove rust and scale, as well as roughening the surface of the part, thus increasing surface area and increasing adhesion. Excessively rough surfaces can result in poorer adhesion because of a thin prime coat on the peaks and the possibility of air inclusion in the valleys. Freshly cleaned metal surfaces are more active and better adhesion is generally obtained Poorer adhesion results if the vinyl plastisol is underfused. When poor adhesion is obtained and it is known that adhesion is generally good with a given plastisol, primer and metal combination, one should generally look first for impurities on the metal surface. Secondly, check for primer contamination. If the primer pulls loose with the plastisol from the metal surface, one should suspect insufficient primer bake or one of the above problems. If the plastisol pulls from the primed metal, one should suspect insufficient plastisol fusion or excessive primer bake.
