Two molecular defoaming products based on Gemini surfactant technology developed by Air Products for use in a broad array of applications are providing formulators with the way to achieve a flat, smooth, defect-free coating. Surfynol MD-20 and Surfynol MD-30 defoaming agents together present formulators with an answer to the challenges presented by microfoam and macrofoam in their finished product. Specifically, Surfynol MD-20 defoamer combats microfoam, while Surfynol MD-30 defoamer's expertise is addressing macrofoam. The two products are molecular defoamers that are surface active and break foam at the molecular level by attacking the different mechanisms of foam stabilization. Both Surfynol MD-20 and MD-30 defoamers are silicone and hydrophobic silica free.
