Foam is a persistent challenge to formulators and applicators. The selection of the proper defoamer or deaerator can greatly reduce a formulator's frustration and improve the quality of the finished system. Air Products offers a full spectrum of defoamer chemistries including organic oil, mineral oil and silicone-based as well as our own unique molecular defoamers based on Gemini surfactant technology. Our siloxane based deaerators are designed to eliminate foam, pinholing and solvent popping problems in water-based coatings in demanding situations such as application by spray technologies.
