Estimating the term…
The present invention generally relates to a dispersion comprising a plurality of core-shell particles, wherein the core comprising non-fluorinated polymer and the shell comprises fluorinated polymer. It also relates to the use of the said dispersion as an additive in a coating formulation in at least 10 wt %, wherein substrates coated with said coating formulation exhibit improved solar-reflective and anti-dirt properties. In preferred embodiments, the said core comprises methyl methacrylate monomer and the said shell comprises hexafluorobutyl acrylate, hexafluorobutyl methacrylate, tridecafluorooctyl arylate or perfluorooctyl acrylate.
A dispersion comprising
-19. (canceled)
A method of increasing total solar reflectance (TSR) of a substrate comprising the step of forming a coating of a mixture of a dispersion with a coating material on a surface of said substrate, wherein said dispersion comprises a solvent with a plurality of core-shell particles disposed therein, said core-shell particles having at least one non-fluorinated polymer in the core and at least one fluorinated polymer or fluorinated copolymer in at least one shell layer of the shell, and said core-shell particles forming a solid content of at least 10% of the dispersion.
A coated article comprising a layer of a dispersion coated thereon, said dispersion comprises a solvent with a plurality of core-shell particles disposed therein, said core-shell particles having at least one non-fluorinated polymer in the core and at least one fluorinated polymer or fluorinated copolymer in at least one shell layer of the shell, and said core-shell particles forming a solid content of at least 10% of the dispersion.
