Foaming is an undesirable side effect of many industrial processes as it can reduce processing and storage capacity, decrease operating efficiencies, and create problems with product quality and performance. To effectively control the many disadvantages of undesirable foam, it is necessary to chemically break the films of liquid which surround the bubbles of gas released in processing with a defoamer, or to prevent the foam films from forming in the first place with an antifoam.

Silicone-based foam control additives are often the most cost-effective and efficient options for preventing and controlling foam. Due to their low surface tension, silicones spread evenly and rapidly over a foam film, facilitating penetration and collapse of the foam. They also possess the advantage of being non-contaminating, since they are inert and are typically effective at much lower concentrations than non-silicone defoamers.

Within our complete Foamkill™ line, Crucible offers several types of silicone defoamers and antifoams which offer highly effective foam control in a variety of applications and operating conditions. These include:

  • 100% active silicone compounds for nonaqueous and certain aqueous systems (detergents, hydrocarbon scrubbing, cutting oils, glycol formulations, etc.)
  • Silicone emulsions for easy dispersion in aqueous media
  • Solvent dispersions primarily for nonaqueous paints, coatings, inks, & oil & gas applications
  • Ready-to-dilute silicone concentrates for general foaming applications
