Adhesion

The force which causes two surfaces to stick together. The sticking together of surfaces in contact with each other. The bonding of materials with adhesives (glues, cements, binders, etc), in which the intermolecular forces between adhesive and adherend provide the bonds. The sticking together of two metals as a result of compressing them together. The sticking together of two dissimilar metals because of electrical transference of electrons. The ability of paint, Primer, or glue to stick to the surface to which it is applied. The ability of a tire to grip the surface of the road. Mutual forces between two magnetic bodies linked by magnetic flux, or between two charged non-conducting bodies which keeps them in contact. Intermolecular forces which hold matter together, particularly closely contiguous surfaces of neighboring media, e.g., liquid in contact with a solid.
