Estimating the term…
An aqueous composition contains an olefinic polymer having an olefin portion that is substantially saturated and anionic functionality imparting water dispersibility. The olefinic polymer can be prepared by reacting a saturated or substantially saturated olefin polymer with a reactant that provides the water-dispersing functionality. The composition can be an adhesion promoter that provides excellent adhesion of subsequent coating layers to olefinic substrates like TPO or an additive in a different coating composition, which may be a curable coating composition, especially a primer composition, to provide excellent adhesion to olefinic substrates like TPO.
An aqueous composition comprising a polymer comprising anionic groups, a substantially saturated, predominately hydrocarbon polymer portion and at least one further portion selected from the group consisting of (poly)ester blocks, poly(alkylene oxide) blocks and combinations thereof.
