    摘要： The present technology provides a UV curable coating composition, methods for forming a photocured coating on a substrate, and articles that include a substrate and a photocured coating. The UV curable coating composition includes an ethylenically unsaturated polymerizable compound, a functionalized siloxane compound, and optionally a micronized inorganic particle(s). The cured coating may provide improved dirt and/or brake dust pick-up resistance.

    摘要： This invention relates to novel non-isocyanate siloxane-modified glycidol carbamate (GC) resins and coating compositions containing them. The non-isocyanate siloxane modified GC resins of the invention comprise the reaction product of at least one organic polyisocyanate, glycidol, and at least one bis(hydroxyl alkyl)-terminated polydimethylsiloxane. The coating compositions of the invention comprise at least one non-isocyanate siloxane modified GC resin of the invention and at least one curing agent. The invention also relates to methods of making the resins of the invention and coatings containing them. The invention also relates to a fouling-release (FR) coating system comprising the coating compositions of the invention and methods of applying said FR coating systems to substrates. The invention also relates to articles of manufacture comprising a coating composition of the invention and a method of making such articles.

    摘要： Curable silsesquioxane polymers are described comprising a core comprising a first silsesquioxane polymer and an outer layer comprising a second silsesquioxane polymer bonded to the core. The silsesquioxane polymer of the core, outer layer, or combination thereof comprises reactive groups that are not ethylenically unsaturated groups. The first silsesquioxane polymer of the core is bonded to the second silsesquioxane polymer of the outer layer via silicon atoms bonded to three oxygen atoms. In some embodiments, the outer layer has a higher concentration of reactive groups than the core. In this embodiment, the core may be substantially free of reactive groups. In other embodiments, the core has a higher concentration of reactive groups than the core. In this embodiment, the outer layer may be substantially free of reactive groups. The core and outer layer each comprise a three-dimensional branched network of a different silsesquioxane polymer. The silsesquioxane polymers of the core and outer layer may be homopolymers or copolymers. Also described are methods of preparing curable silsesquioxane polymer comprising a core and outer layer bonded to the core, articles comprising curable or cured compositions comprising the silsesquioxane core/outer layer polymers, and methods of curing.
