Product Overview
CP 349W is a water-based adhesion promoting additive for coatings, paints, inks, and adhesives. This dispersion of chlorinated polypropylene contains 2-amino-2-methyl-1-propanol as the neutralizing amine, making it more compatible with waterborne resins and more useful as a stir-in additive. CP 349W also contains 5% ethylene glycol to improve the freeze resistance of the dispersion.
