Air Products, Allentown, Pa., introduced new Dynol 960 and Dynol 980 superwetting surfactants and Airase 4500 defoamer for indirect food contact compliance.
Dynol 960 and 980 surfactants were designed to meet the growing need for high-performance waterborne coatings, inks and adhesives for low energy surfaces. These new, low-foaming optimized siloxane superwetting surfactants provide premium equilibrium and dynamic surface tension reduction as well as improved flow and levelling for difficult-to-wet surfaces.
Meanwhile, the Airase 4500 defoamer is a proprietary organic oil defoamer that does not contain added mineral oils, hazardous air pollutants or alkyl phenol ethoxylates, making it suitable for a broad range of applications. Compliant with European food contact regulation, theAirase 4500 defoamer is designed to eliminate foam, pinholes and entrapped air in water-based inks, adhesives and coatings without generating surface defects.
