Adhesion measurement
By testing adhesion during the coating process, you can assess the bonding strength between the substrate and the coating, as well as between multiple successive layers (e.g., paint layers).
testing adhesion of coatings
Most products have a protective or decorative coating. Poor adhesion can lead to costly repairs or complete rework. The quality of adhesion not only affects how well the coating sticks but also impacts corrosion formation. Corrosion often begins where the coating has detached from the substrate. Adhesion testing is simple with a cross-cut tester: first, the coating is cut through with defined, perpendicular cuts that intersect. Then, loose edges and any flakes are removed, and the cross-cut pattern is visually assessed by comparing the damage pattern with the corresponding illustrations in the standard.
importance of adhesion measurement in quality control
Adhesion measurement is a critical part of quality control in painting and coating processes. Ensuring strong adhesion helps maintain the durability and appearance of the surface treatment. Using proper adhesion testing tools allows professionals to detect weak bonding early, preventing failures and extending the lifespan of coatings. This contributes to a flawless finish and reduces maintenance costs over time.
