ENHANCED DURABILITY, EXCELLENT FOAM CONTROL 

Silicone Antifoam Agent

For many applications and industries, foam isn’t just a nuisance, it’s a problem. Excessive foaming can cause vessels to overflow, interfere with processes and packaging, and damage materials or equipment. Silicone antifoam agent can help solve all of these challenges efficiently and effectively by preventing and minimizing foam.

In the same way, for different applications, silicone antifoam agent and foam control agents are available in two different forms:

  • Compounds – 100% active content, used in non-aqueous media or to make aqueous emulsions.
  • Emulsions – with from 10 to 60% active content, containing surfactants and water.

Application & Benefit

Defoamer agents that destroy foam
Antifoam agents that prevent excessive foam
De-aerating agents that control bubbles from developing too much

PHD48 is high-performance antifoam emulsion available for multiple uses in the textile industry,the product generally creates exceptional durability at low add-on levels, and performs effectively at much lower use levels than other silicone antifoams on the market. Additionally, PhD silicone antifoam gives a homogeneous dilution in water or bath formulations with no oiling or agglomerates.

  • Effective performance at significantly lower use levels than competitive antifoams
  • Outstanding durability at low add-on levels
  • Excellent foam control at ambient and elevated temperatures
  • Rapid foam knockdown
  • Long durability in acidic or alkaline conditions
  • No oily spots or agglomerates when diluted with water
  • Easily dispersed in hard water

Active Content, %: 48

Chemical Basis: Copolymer of polysiloxane, silicone resin, silica, dispersant and stabilizer

pH value: 6.5 to 8.5

Form: Liquid

DSA20 silicone antifoam is highly potent antifoam emulsion that offers excellent foam control as well as excellent compatibility in a variety of surfactant concentrates and foaming systems. Compared to common silicone defoamers, it offers exceptional foam knockdown and durability, and greater compatibility in difficult surfactant systems, e.g., such as those rich in solvents and/orelectrolytes.

  • High antifoam efficiency in surfactant-rich systems
  • Rapid foam knockdown
  • Long-term foam inhibition
  • Easy dispersion in all foam systems
  • Easy dispersion in hard water
  • Long durability in acid and alkaline conditions
  • No oily spots or lumps when diluted with water
  • Compatibility with a variety of surfactant concentrates

Active Content, %: 20

Chemical Basis: Copolymer of polysiloxane, silicone resin, silica, dispersant and stabilizer
