Fundamentals and Characterization of Scratch Resistance of Automotive Clear Coats

Resistance to scratch and mar damage has been emphasized by both OEMs and consumers as a critical factor to maintain a vehicle’s appearance over lifetime. As coating formulators improve the quality of their products, the traditional testing methods used in the paint industry are not always capable to reliably show the improvement in mechanical properties and scratch resistance. In this webinar, fundamental methodologies including instrumented indentation and scratch testing at multiple scales are used to better understand the scratch and mar behavior of automotive topcoats.
