I have been experiencing flow and leveling surface defects, such as orange peel, with my waterborne coating formulation. How can I overcome this problem?
← Back to Paints and Coatings
Orange peel is a common surface defect seen when waterborne coating formulations have poor flow and leveling. Air Products’ superwetters, Dynol® 360 and Dynol™ 604 surfactants, not only help reduce orange peel and improve flow and leveling but they also increase gloss in many types of industrial coatings. If higher water-solubility is needed in the additive, then Surfynol® 440 and SE-F surfactants should be tried, as they provide a balance between very good dynamic wetting and excellent system compatibility.
