摘要:
A method for producing a multilayer two-tone finish on a substrate such as an automobile or truck body or parts thereof. The method includes the steps of applying two different primers to a substrate, applying an accent color to a portion of the substrate and baking the applied coatings. The accent area is then masked and a main color is applied to the unmasked portion of the substrate. The mask is then removed from the accent color area, a clearcoat is applied to the applied main and accent colors and the substrate is baked to dry and cure the applied coating compositions. The clearcoat composition carbamate material, a curing agent and a hydroxy functional silane component. The method and the clearcoat composition provides a substantially durable and wrinkle free appearance and excellent adhesion to waterborne and solventborne basecoats, baked or unbaked.
