ABSTRACT:
Two component (2K) waterborne polyurethane coating compositions which when cured achieve excellent anti-graffiti properties at low VOC level (below 100 g/L) are disclosed. The composition comprises (A) a fluorinated polyol and optionally a non-fluorinated polyol; and (B), a blend of polyisocyanates comprising a hydrophilically modified trimer of hexamethylene diisocyanate (HDT) and a hydrophilic ally modified trimer of isophorone diisocyanate (IPDT). The glass transition temperature of the ambient cured coatings, crosslinked network structure, and fluorine content at the surface enable excellent anti-graffiti properties. The waterborn coatings of the invention have excellent recoatability and exceptional chemical resistance.
