ACRYLIC POLYMERS, CURABLE FILM-FORMING COMPOSITIONS PREPARED THEREFROM, AND METHOD OF MITIGATING DIRT BUILD-UP ON A SUBSTRATE |
摘要 |
The present invention is directed to acrylic polymers comprising: (i) hydroxyl functional groups; (ii) polydialkylsiloxane functional groups; and (iii) silica nanoparticles that are chemically bonded to and pendant from the acrylic polymer. The present invention is further directed to curable film-forming compositions comprising acrylic polymers, and to coated substrates comprising the curable film-forming composition applied to at least one surface of the substrates. The present invention is also drawn to methods of mitigating dirt build-up on a substrate, comprising applying to at least a portion of the substrate the curable film-forming composition described above and at least partially curing the curable film-forming composition. |
