Solve foaming problems with pinpoint accuracy with Airase™ Structured Siloxane Defoamer Line

The Airase Structured Siloxane Defoamer Line (SSDL™ defoamers) consist of seven defoamers, each designed to have predictable performance relative to each other to allow formulators to take a systematic approach to defoamer selection. Each product has a different balance of defoaming strength and formulation compatibility for optimal defoaming performance in different applications.

Airase 5100 and 5200 defoamers are both very strong defoamers, designed for applications where strong defoaming is required but compatibility is not an issue or the defoamers can be incorporated with high shear. Airase 5300 and 5400 defoamers are strong defoamers with good compatibility for applications where shear stability is required. Airase 5500 and 5600 defoamers have good compatibility for applications where balance between defoaming and surface defect-free appearance is needed, while Airase 5700 defoamer is designed for applications that are very sensitive to craters and other surface defects.

If one product in the line does not give sufficient foam control, the formulator can try the next product in the line (lower number) for stronger defoaming performance. Similarly, if a product in the line gives film defects, such as craters or fisheyes, the next product in the line (higher number) should be more compatible in the formulation. This performance predictability is summarized in Figure 1.
