US Classification:

427372200, 427402000

Abstract:

This invention relates to a method for maximizing the stone chipping resistance and scratch resistance of a multi-layer finish on an automotive substrate. A colored basecoat is applied to the substrate and directly on top of the basecoat is applied a protective clearcoat having a fracture resistance about equal to or above 26 mN and a plastic deformation resistance about equal to or above 30 mN/μm. The resultant coating in addition to being durable to the elements and having excellent appearance produces a finish with an outstanding balance of scratch and stone chip resistance after application.
