ASTM D3359-09

ASTM D3359-09 is a standard test method used to measure how well a coating or paint sticks to a surface. It involves creating a grid of cuts through the coating and then applying tape over it. When the tape is pulled off, the amount of coating that comes away indicates the adhesion strength. This helps determine if the coating is properly bonded and suitable for its intended use, ensuring durability and performance. The standard provides a consistent way to assess adhesion across different materials and coatings.
