NIST and industry partners create new lab test to provide quantitative data on the scratch and damage resistance of automobile polymer clearcoat layers. Compare this with the 2 common methods currently used that provide only qualitative assessments: one is a rotating wheel of brushes to simulate car wash damage, and the other is a robotic ‘finger” moving back and forth to mimic damage from human contact and abrasive surfaces. Both of these “methods only assess clearcoat performance based on appearance, a qualitative measure where the results vary from test to test, and they don’t provide the quantitative data that scientifically helps us understand what happens to auto finishes in real life.”
