Abstract: 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.

Abstract: A coating composition includes a first composition comprising a polymeric binder comprising a hyperbranched polymer or a polymer comprising a covalently bonded surfactant; a second composition comprising a coagulating agent; and an additive comprising an intumescent agent, a vibration damping agent, an insulation agent, or a combination of two or more thereof; wherein: the additive is present in the first composition, the second composition, or both the first and second compositions; the intumescent agent comprises an acid source, a carbon source, and a gas forming agent; the vibration damping agent comprises a first filler; the insulation agent comprises a second filler; and the first composition and the second composition are configured to form a coating within 30 seconds of application to a substrate, and the coating is non-sagging, water-resistant, and dry-to-the touch.

Abstract: An essentially chromium(VI)-free, chromium(III)-containing corrosion resistant conversion solution, or layer thereof for treating metals such as zinc, zinc alloy, aluminum, or aluminum alloy substrates. The conversion solution, is substantially free of chromium(III)-chelates, is capable of producing thick conversion films even at low temperatures, has good corrosion resistance, and is self healing with regard to scratches and the like.
