Primer Metal

Primer For Metal We offer Primer For Metal. If good adhesion to metal 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. Solvent based primers can generally be thinned with methyl ethyl ketone (MEK). 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 191A C for five (5) minutes or longer. Shorter bake times and lower bake temperatures can provide good and sufficient adhesion. 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 more..
