The ASTM D7187-20 standard introduces a nano-scratch method for the measurement of scratch/damage resistance performance of Coatings. This method quantitatively evaluates the scratch performance of coatings by analyzing the relationship between surface damage and Gloss changes. The standard applies to polymer-based coatings such as paints and varnish, and provides a technical means for accurate measurement of coating scratch resistance to ensure Coatings performance and durability.
