What are the composition and structure of silicone antifoaming agents?

Silicone antifoaming agents are a class of compounds that can stabilize foam while effectively reducing surface tension. They typically consist of organic molecules containing silicon, formed by incorporating silicone moieties into surfactants. These compounds play a crucial role in various industrial processes, spanning fields such as plastics, coatings, printing, and pharmaceuticals.

What is the difference between non-silicone defoamers and silicone‑based organic silicon defoamers?

In certain industrial processes, foam often poses significant challenges, reducing productivity and compromising product quality. To address this issue effectively, non‑silicone defoamers are an excellent choice. Currently, silicone‑based defoamers are widely employed; while they offer strong emulsion‑breaking performance, they can readily leave silicone residues, leading to long‑term quality concerns. At present, no truly ideal non‑silicone defoamer is available in China, and a comprehensive integration of relevant emulsion‑breaking theories was essential to develop the T‑30C non‑silicone defoamer. Following trials by several manufacturers, it has delivered highly satisfactory results.

What is a non-silicone defoamer?

Non-silicone defoamer, formulated with aldehydes and oleic acid complexes. Off-white with a yellow tinge; non-ionic. Suitable for PCB circuit boards (during development, ink removal, and wastewater stages). Also applicable to aluminum processing, as well as emulsion breaking and foam suppression in various wastewater treatment and industrial water systems, and for demulsification in cooling‑circulation water systems and other water‑treatment units.

What causes defoamer-induced oil floating and whitening?

Using defoamers to bleach oil is a highly problematic issue, as it often indicates poor defoamer quality and can lead to adverse effects in severe cases. Many customers adopt a straightforward approach: assessing whether the defoamer used for oil bleaching is excessively aggressive. Accordingly, the following section summarizes several methods employed by silicone‑based defoamer manufacturers to determine if a defoamer will cause oil bleaching.
