AI Overview
Hydroxy compound antifoams are specialized, often non-silicone, defoamers (e.g., AF-713, AF-502) designed to control foam in high-temperature, acidic, or alkaline environments, such as wastewater treatment and pulp/paper processing. These agents effectively disperse in water, breaking existing foam and preventing future foam generation.
Key Characteristics and Applications
- Composition: These products are often based on polyethers or fatty acid esters containing hydroxyl (OH) groups.

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
