Defoamers

Blue Foam

Clearwater offers the Kemira portfolio of environmentally and process-friendly defoamers for all municipal and industrial applications.

Our versatile KemFoamX product line includes different chemistries for various foam scenarios. We carry different types of defoamers suitable for a variety of industries, from oil-based defoamers to silicon-based defoamers.

Water-Based Foam Control

Kemira water-based 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. Kemira water-based 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 waste water treatment, cooling towers, fiberglass mat manufacturing, and as a filtration aid in conjunction with Kemira polymers.

Water-Extended Oil-Based Foam Control

Kemira 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 waste water.

Water-based Product Description

KemFoamX 1195 General purpose; oil–free; nonylphenol ethoxylates–free; water–based; minimizes

foam in waste treatment applications

KemFoamX 1196 Low toxicity blend that has excellent performance on a cost–basis

Oil-Based Foam Control

Kemira 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. Kemira 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, waste water treatment and gas stripping.

Oil-based Product Description

KemFoamX 6695 Non–silicone; oil–based; effectively controls foam coming from flotation applications

KemFoamX 6698 Non–silicone; highly dispersible; oil–based; effectively controls foam coming from flotation applications

Oil-Free Foam Control

Kemira 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.

Kemira 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. Their versatility extends to numerous other applications including waste water treatment, adhesives and digesters.

Silicone-Based Foam Control

Kemira 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.

Kemira 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 waste water treatment, cement, detergents, chemical processes and agricultural to mention a few.

Silicon-free based Product Description

KemFoamX 5520 General purpose, mineral oil–free, synthetic, liquid defoamer–de–aerator effective in many applications

KemFoamX 9920 Silicone–free defoamer used in severe pH applications

Food-Grade Foam Control

Kemira food-grade defoamers are FDA 173.340 compliant, but may additionally comply with other food-related regulations. They may originate from many of the above technologies with their associated advantages. Consult your Kemira representative for specific applications.
