The contact angle is the angle formed at the junction where a liquid interface meets a solid surface, indicating the degree of wettability of the solid by the liquid. It is a critical parameter in understanding surface interactions, influencing phenomena such as adhesion, spreading, and capillarity.

Solid surface materials are durable, non-porous composites primarily made from acrylic, polyester resins, and natural minerals, offering a seamless and versatile solution for countertops, wall cladding, and other architectural elements. Their ability to mimic the appearance of natural stone while providing superior resistance to stains, bacteria, and impact makes them a preferred choice in both residential and commercial settings.

Surface interactions refer to the various physical and chemical phenomena that occur at the interface between two phases, such as solid-liquid, solid-gas, or liquid-liquid. These interactions are crucial in determining the properties and behaviors of materials, influencing processes like adhesion, catalysis, and wetting.

surface interactions

Adhesion is the tendency of dissimilar particles or surfaces to cling to one another due to intermolecular forces. It plays a critical role in various natural and industrial processes, such as the sticking of water droplets to leaves and the bonding of materials in construction and manufacturing.

spreading

Capillarity, also known as capillary action, is the ability of a liquid to flow in narrow spaces without the assistance of external forces, often against gravity. This phenomenon is driven by the adhesive force between the liquid and the surface of the material and the cohesive forces within the liquid itself.
