In the coating applications, liquid surface tension measurement is critical, which include liquid-air interfacial tension and liquid-substrate (solid) interfacial tension. Contact angle measurement is a common method for the surface tension measurement; however liquid surface tension might not be available for the measurement. Pendant drop method is a good for this purpose.
