Patent ID: 8568888

Claim:
A surface-protective coating composition, comprising: (1) a first component comprising: a globular dendritic polymer having a peripheral cross-linkable hydroxyl functionality of about 32 to about 64; optionally, an acrylic compound having a peripheral cross-linkable hydroxyl functionality of about 2 to about 6; optionally, a plurality of metal oxide nanoparticles optionally encapsulated in a cross-linkable hydroxyl functional polymer and/or a cross-linkable hydroxyl functional fluorosurfactant; optionally, a sterically hindered amine light stabilizer; optionally, a UV absorber; optionally, a cross-linking catalyst; and a first substantially anhydrous solvent in which the above materials are dissolved or, in the case of the nanoparticles, are dispersed; and (2) a second component comprising: a cross-linking agent capable of reacting with hydroxyl groups; and a second substantially anhydrous solvent which may be the same as or different from the first substantially anhydrous solvent, wherein the first and second components are mixed together to form the coating composition.
