Unfortunately, there is inadequate basic scientific understanding of the variable affecting adhesion. As adhesion is dependent on the wettability, the wetting agent is often added to coating formulation to reduce the surface tension and improve the spreading of the coating. It is commonly divided into mechanical interlocking and physical and chemical bonding. Five reasons water is so important to your health. Cohesion gives rise to surface tension, the capacity of a substance to withstand rupture when placed under tension or stress. Items to be considered in determining its peel adhesion for these applications include: Plants use capillary action to bring water up the roots and stems to the rest of the plant.
