STEPAN MWA-260 is a biodegradable, nonionic surfactant that exhibits low foaming properties and excellent wetting action. STEPAN MWA-260 resists foam development even under extreme or prolonged agitation; and it is completely non-foaming above 25C. It can be used as an emulsifier and lubricant in synthetic and semi-synthetic metalworking fluids. STEPAN MWA-260 can be used as a component of lubricants, gear and chain oils, metalworking fluids, hydraulic fluids, and plasticizers.
