Primers

Primers are essential in increasing the adhesion of the plastisol onto metal surfaces. Without primers plastisols normally have very little adhesion to bare metal. Loes manufactures two series of solvent-based primers, PA3011 and the 8400 Series. The 3011 series can be used when the substrate is either heated or cold dipped, and is approved for use with MIL-P-20689D Plastisols. The 8400 series should be used only if the substrate is preheated, and is more economical. Primers are clear and non-settling, and can be colored to distinguish application.
