Defoamers

Defoamers are process-friendly dispersions of long-chain fatty alcohols which easily emulsify with water. They provide good de-aeration and efficient foam suppression over a wide range of pH (3-10) at temperatures up to 60˚C (140˚F), leaving no residual material in the system. Defoamers are inherently biodegradable and do not contribute to VOC’s. The products constitute an economic and sustainable choice for a variety of applications, especially in wastewater treatment, cooling towers, fiberglass mat manufacturing, and as a filtration aid in conjunction with polymers.

Water-extended oil-based foam control

water extended oil-based defoamers include amide/silica, and silicone chemistries, which generally work at higher temperatures than water-based defoamers and tend to be more persistent in handling difficult foaming problems. While similar to oil-based defoamer performance, they are generally lower in cost and contribute less oil than straight oil-based defoamers. Applications include a variety of uses in paper, board, coatings, pulping, and wastewater.

Food-grade foam control

Food-grade defoamers are FDA compliant, and may additionally comply with other food-related regulations. They may originate from many of the above technologies with their associated advantages. Consult your  representative for specific applications.

Oil-based foam control

  • oil-based defoamers consist of a 100% active dispersion in mineral oil and can be used in more severe foaming applications and persistent foam reduction.
  • The products come as emulsifiable in water and suitable for a very wide range of applications, or as insoluble and very efficient in high foaming applications.
  • oil-based defoamers are cost efficient and well suited for a variety of processes at temperatures up to 90˚C. Primary applications include production of inks, paints and coatings, textiles, wastewater treatment and gas stripping.

Oil-free foam control

  • oil-free defoamers consist of 100% active concentrates of synthetic ester or polyols and have a very good de-aeration capacity. They are emulsifiable in water and due to the nature of the carrier component they are able to suppress foam re-generation even longer than oil-based products.
  • oil-free defoamers do not coagulate pigments and do not induce swelling of rubber print equipment, which makes them especially suitable in pigment slurries, inks and gloss paints.
  • heir versatility extends to numerous other applications including wastewater treatment, adhesives and digesters.

Silicone-based foam control

  • silicone-based defoamers are available either as concentrates with 100% active substance, or as lower concentrated emulsions. They contain no mineral oil, amides or nonylphenol ethoxylates (NPE) and leave minor residue in the process.
  • silicone-based defoamers are efficient and process friendly in numerous areas of industry. They are the products of choice in the most severe foaming conditions, performing at temperatures up to 100˚C.
  • Typical applications are wastewater treatment, cement, detergents, chemical processes and agricultural to mention a few.
