| abstract |
Coating compositions are provided which include a polysiloxane comprising at least one reactive functional group, at least one material comprising at least one reactive functional group, and at least one boron-containing compound. Also provided are multi-layer composite coatings formed from a basecoat deposited from a pigmented coating composition and a topcoat applied over the basecoat, the topcoat deposited from the aforementioned coating composition. Methods for repairing a multi-layer composite coating and coated substrates are also provided. The compositions of the invention provide highly scratch resistant coatings, particularly highly scratch resistant color-plus-clear coatings, which have excellent intercoat adhesion to subsequently applied coating layers. |
