CP 347W

CP 347W is a highly compatible water-based dispersion of chlorinated polyolefin that is used as a stir-in adhesion promoting additive to inks and coatings.
Product Overview
CP 347W is a water-based dispersion of chlorinated polypropylene that is neutralized with 2-amino-2-methyl-1-propanol. The neutralizing amine in this dispersion makes it more compatible with waterborne resins and better suited for use as a stir in additive. When CP 347W is included in a coating, ink, or adhesive formulation it improves adhesion to low energy plastic surfaces and metal. As a water-based dispersion, CP 347W is an ideal adhesion promoting additive for applications that require low VOC content.
