CP 343-1-100% is a solid powder form chlorinated polyolefin that is used in solution based primer formulations for untreated polypropylene, TPO, and metal.
CP 343-1-100% is a chlorinated polypropylene polymer in solid powder form. This polymer is also commercially available in solution. CP 343-1-100% is most often used in solvent based primer formulations that are used on untreated polypropylene, aluminum, and galvanized steel. Primers formulated with CP 343-1-100% show excellent humidity resistance and are most commonly used for improving adhesion of coatings, paints, adhesives, and inks to low energy surfaces.
