Abstract: The present invention is directed to a coating composition particularly useful as a clear coating applied over a pigmented base coating, wherein the clear coating has improved resistance to marring and to acid etching when exposed to natural weathering conditions. The clear coating is particularly useful as an automotive OEM clear coating or as a refinish clear coating. The coating has two components. Component A of the coating composition includes a melamine and an acrylosilane polymer of a polymerized monomers mixture, which includes an alkyl methacrylate, an alkyl acrylate, cycloaliphatic alkyl methacrylate, cycloaliphatic alkyl acrylate, styrene or any mixture of these monomers; hydroxy alkyl methacrylate, hydroxy alkyl acrylate or any mixtures of these monomers; and a mono-ethylenically unsaturated silane monomer. Component B of the composition includes an organic polyisocyanate as a crosslinking agent.
