Air Products' Airase 4750V and 4800 oil-based defoamers are effective foam control additives for use in a wide variety of applications, including architectural and industrial coatings, inks, and adhesives. Airase 4750V is a proprietary vegetable oil-based defoamer, whereas Airase 4800 is a 100% active, mineral oil-based defoamer. Both defoamers are designed for excellent film compatibility with sustained, long-term defoaming performance and are currently available in North America.
"With the launch of these new Airase defoamers, we continue to expand our defoamer offering so that we are able to offer formulators a wide variety of options to address their foam control needs," said Chris Henkee, global marketing manager, Additives, for Air Products. "With defoamers based on mineral oils, organic oils, siloxanes, and Air Products' own unique Gemini molecules, we are able to offer the formulator a means to quickly optimize formulation performance, minimize reformulation time and effort, keep formulation costs under control, or simply use products with specific qualities that can limit certain environmental effects."
Air Products is also highlighting its portfolio of DynolTM superwetting surfactants, which provide both low equilibrium and dynamic wetting and are engineered for system compatibility as well as contributing little or no foam. Uniquely, Air Products is proud to offer four different classes of superwetters, each class with different attributes based on the nature of the superwetting surfactant molecules employed. The Dynol superwetting surfactants are particularly useful in formulations designed to be used in high speed applications or to wet difficult-to-wet surfaces such as plastics, wood, or even oil-contaminated metals.
Air Products also offers a complete line of high performance ZetaSperse® dispersants for resin-free and resin-containing systems as well as a variety of performance enhancing additives for dispersion formulation.
