Adhesion strength refers to the ability of two surfaces to stick together. It is an important property in materials science, affecting how well adhesives, coatings, and paints bond to surfaces. Factors influencing adhesion strength include surface roughness, cleanliness, and the type of materials involved. In practical applications, high adhesion strength is crucial for products like glues, tapes, and paints, ensuring they perform effectively. Conversely, low adhesion strength can lead to failures, such as peeling or delamination. Understanding adhesion strength helps engineers and manufacturers create better products and improve their durability.
