1 Eastman chlorinated polyolefinsFormulating with Eastman waterborne CPO adhesion promotersUseful as: Base resins for waterborne adhesion promoter primers Adhesion promoting additives for waterborne coatingsIntroductionThe application of paint to polypropylene and TPO (thermoplastic polyolefin) is difficult because of the poor adhesion of most coatings to these plastics. Eastman CPO adhesion promoters are effective in improving paint adhesion to these substrates. With Eastman CPO dispersions, it is possible to apply an adhesion-promoting primer from a waterborne system or to promote adhesion of a waterborne coating through use as an additive. Physical propertiesEastman CP 310W, CP 347W, and CP 349W are water dispersions of the same CPO resin. Major differences are the neutralizing amine in each dispersion and the presence of ethylene glycol in CP 349W.
