KAG 1575 Silicone Antifoam Emulsion
Product Description
KAG 1575 silicone antifoam emulsion is a highly potent silicone antifoam emulsion that uses novel silicone materials to provide excellent foam control as well as a high level of compatibility with a variety of surfactant systems.Compared to common silicone defoamers, KAG 1575 silicone antifoam emulsion provides an exceptional initial foam control when first applied to a' foaming system, as well as the ability to maintain its foam control properties for longer periods. As a result, KAG 1575 silicone antifoam emulsion can be used at lower use levels than conventional silicone antifoams. Its improved compatibility is particularly evident when used in difficult surfactant systems such as those that have high surfactant concentrations, and those that contain electrolytes.
Key Features and Typical Benefits
- High anti foam potency
- Rapid defoaming when the antifoam is initially applied to the foaming system
- Long lasting foam inhibition
- Easy and rapid dispersal in aqueous systems
- Performs well over a broad pH range

How to Use
KAG 1575 silicone antifoam emulsion is a medium viscosity emulsion that is intended to be used in water-based systems. It can be added directly to these systems without pre-dilution and mixed with slow to moderate agitations to ensure a complete and homogenous dispersion.The use levels for KAG 1575 silicone antifoam emulsion when used in the final foaming system will be dependent upon the nature of the foaming system and the type of agitation that generates the foam. A recommended starting point is addition of sufficient KAG 1575 silicone antifoam emulsion that would give between 5 ppm and 50 ppm of antifoam (based on % silicone solids) in the final foaming formulation.
As with any aqueous-based formulation, it is recommended to confirm that the foam control agent remains dispersed once added to the pesticide formulation.
Performance Data
An example of foam control efficiency and durability for KAG 1575 silicone antifoam emulsion is shown in Figure 1. Solutions of Roundup Ultra (2.5%) containing either 25 ppm of a standard silicone antifoam, or 10 ppm KAG 1575 silicone antifoam emulsion were agitated on a wrist action shaker for 1, 15 and 60 minutes at a temperature of 22°C. Foam height was measured after each time interval at 1 minute after shaking.KAG 1575 silicone antifoam emulsion provides excellent foam control relative to the standard silicone antifoam, but at less than half the use level (10 ppm vs. 25 ppm). Although the standard silicone antifoam looses effectiveness after 15 minutes of agitation, KAG 1575 silicone antifoam emulsion provided a high level of foam control, even after 60 minutes of agitation, demonstrating the superior durability properties of this unique antifoam agent.
