An Adhesion Test is a method used to evaluate how well a coating, paint, or adhesive sticks to a surface. This test helps determine the durability and performance of the material under various conditions. It is commonly used in industries like construction, automotive, and manufacturing to ensure quality and reliability. The test typically involves applying a specific force to a coated surface and measuring the amount of material that detaches. Various techniques, such as the cross-hatch test or pull-off test, can be employed to assess adhesion strength. Results guide improvements in product formulation and application methods.
