AI Overview
Defoamers for cyclic shear systems, such as metalworking fluids (MWF), industrial cleaners, and textile processing, require high shear stability to prevent the silicone or polyether active ingredients from breaking down under constant mechanical agitation. These specialized defoamers maintain efficiency under high pressure, temperature, and varying pH levels.
Top Defoamers for Cyclic Shear Systems
- AF-716 Silicone Defoamer: A silicone oil/hydrophobic particle emulsion designed for high-shear environments like fully synthetic, semi-synthetic, and emulsified oil cutting fluids.
- RP-6307 High Temperature Defoamer: A specialized silicone grease system with a tailored emulsifying system, ensuring high stability in metal cutting fluids and other shear systems.
- RP-6305 Water Based Defoamer: Offers excellent shear stability and long-term foam suppression for synthetic/emulsion cutting liquid systems, with a recommended dosage of 1–20 ppm.
- AF-717 Silicone Antifoam: Suitable for cutting fluid, providing long-lasting foam inhibition under high shear.
Key Characteristics
- Shear Resistance: The emulsifying system is engineered to prevent the defoamer from separating (breaking) under continuous stirring.
- Compatibility: Designed for high compatibility with water-based systems to avoid surface defects or oily residue on parts.
- High Temperature Performance: Stable at elevated temperatures commonly found in high-speed machining and industrial processes.
