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.

Two component waterborne polyurethane coatings for anti-graffiti application

A hardener composition for use as a component of a two component polyurethane coating composition, comprising a polyisocyanate, a catalyst for promoting reaction of the polyisocyanate with a reactive hydrogen compound, and one or more antioxidants selected from: a first antioxidant comprising one or more of sterically hindered phenol antioxidants and secondary aryl amine antioxidants, and a second antioxidant comprising one or more organophosphite antioxidant, exhibits improved color stability.

Color stability of isocyanates

A method for improving the integrity of a cosmetic film applied to nails or surrounding cuticle surfaces comprising applying to the surface an effective amount of a composition comprising less than 5% by weight of the total composition of a fluorinated oil. The invention also comprises a nail and cuticle conditioning composition and a semi-permanent film forming composition containing the fluorinated oil.
