Coating compositions having improved scratch resistance, coated substrates and methods related thereto |
摘要 |
Compositions are provided which contain (a) one or more polysiloxanes comprising at least one reactive functional group; a plurality of particles; and, optionally, one or more curing agents comprising at least one functional group that is reactive with any reactive functional group of polysiloxane (a). Additionally, a process for applying the multi-component composite coatings described above to a substrate and coated substrates are provided. A process for preparing the coating compositions also is provided. The multi-component composite coating compositions of the invention provide highly scratch resistant color-plus-clearcoatings capable of retaining scratch resistance after weathering.
