Overview
CP 310W is a water-based dispersion of a chlorinated polypropylene polymer. The neutralizing amine in the dispersion is ammonia which lends to faster drying time. This makes CP 310W more useful in priming applications that are air dried prior to application of a topcoat. CP 310W is a low VOC, APEO free dispersion that is well suited for primer formulations used in the automotive industry.
