Surfactants in paint agent". Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or the interfacial tension between a liquid and a solid. In solutions this behavior is known as wetting, and it occurs as a result of surfactants adsorbing to the air/water interface. Soluble surfactants are also capable of forming micelles and other aggregate structures in solution, leading to a stabilizing effect in latex paints. Surfactants in paint are used to change many end properties of a dried paint, as well as to emulsify paints in their liquid state. Surfactants affect a wide array
Surface tension surface tension of both. The surface tension of pure liquid water in contact with its vapor has been given by IAPWS as where both and the critical temperature = 647.096 K are expressed in kelvins. The region of validity the entire vapor–liquid saturation curve, from the triple point (0.01 °C) to the critical point. It also provides reasonable results when extrapolated to metastable (supercooled) conditions, down to at least −25 °C. This formulation was originally adopted by IAPWS in 1976 and was adjusted in 1994 to conform to the International Temperature Scale of 1990. The uncertainty of this formulation is
