AI Overview
Silicone antifoams for fully synthetic systems, particularly water-based or synthetic cutting fluids, typically use silicone oil (polydimethylsiloxane) and hydrophobic silica emulsions to provide high-efficiency, long-lasting foam control in high-shear, alkaline environments. Top choices include specialized emulsions like AF-716 and AF-717, which are engineered for stability in synthetic metalworking fluids and industrial cleaners.
Key Features and Types for Fully Synthetic Systems:
- Aqueous/Synthetic Emulsions: AF-716 and similar silicone water-based emulsions are designed for water-soluble synthetic cutting fluids and cyclical shear systems.
Recommended Products and Applications:
- AF-716 (Silicone Emulsion): Specifically designed for fully synthetic, semi-synthetic, and emulsified oil cutting fluids.
- AF-717 (Silicone Emulsion): Suitable for fully synthetic cutting fluid, industrial cleaning, and antifreeze.
- AF-220S: Suitable for water treatment and adhesion applications, offering high resistance to acids and alkalis.

What is the difference between silicone and non silicone antifoam?
Silicone defoamers are made from silicone oil, while non-silicone defoamers are made from other materials, such as fatty acids, silica, or talc. Silicone defoamers are typically more effective than non-silicone defoamers, and they are also more versatile.Oct 30, 2023

What are the disadvantages of antifoaming agents?
Disadvantages of Silicone Based Defoamers
Silicone-based antifoam is relatively poor durability. Silicone is oil soluble, and it reduces the defoaming effects in oil systems. It is not ideal for long-term high-temperature resistance and strong alkali resistance.Jan 20, 2022
