What effective fluorosurfactant replacements are available for my coatings formulations?
← Back to Paints and Coatings
Because of the environmental and health concerns associated with fluorosurfactants, many formulators are seeking effective alternatives for their coatings. Air Products’ superwetters, Dynol™ 604, Dynol™ 607 and Dynol® 360 surfactants, can relieve the concerns associated with fluorosurfactants because they do not contain bioaccumulative perfluoroalkyl chains. APEO-free and negligible to zero-VOC, Air Products’ superwetters have been proven in extensive testing of actual formulations to effectively outperform fluorosurfactants, silicones and other hydrocarbon surfactants. As organic surfactants, Dynol 360, Dynol 604 and Dynol 607 surfactants have greater resin compatibility that allows for better recoatability and inter-coat adhesion. These novel surfactants can be used alone or in conjunction with other additives, such as Air Products’ Surfynol® products, to achieve broad formulating latitude and optimal product performance in new systems or as a substitute in existing formulations.
