DEFOAMER
Non-silicone oil defoamers for application in fluids concentrates and as tank-side additives
DEFOAMER products from Esti Chem A/S are highly efficient, silicone oil-free dispersions, which are applied in formulated, aqueous products such as industrial cleaners, fountain solutions, water-miscible lubricants, and release agents. DEFOAMERs may be formulated into the concentrate or applied as tank-side additives. DEFOAMER products are available with varying solubility characteristics as show in below table.
All DEFOAMER grades are free from traditional silicone oils, and they have no have a negative influence in subsequent surface finishing processes such as phosphating or painting.

FAQ about defoamer
How can I apply the DEFOAMER products?
The DEFOAMER products can be applied in the fluid concentrate or as tank-side additive to diluted systems. The DEFOAMER products are free from silicone oils and do not cause problems in subsequent surface finishing such as painting. The products exhibit excellent long-term defoaming properties, they are much easier to incorporate into fluid concentrates than silicone oil emulsions, and the tendency to separation during storage is equally much lower than for the silicone oil emulsions.
What is the difference between the various grades?
DEFOAMER 1000 is a very concentrated, high-performance defoamer; it is water-free and contains no biocides. DEFOAMER 45-N, 100-FI and 700 are water-containing defoamers with varying polarity. The 45-N grade is primarily applied in emulsion-based products, the 100 FI is an all-round product applicable in most systems, whereas the 700 grade is mostly applied in synthetic fluids. DEFOAMER 700 is a defoamer with additional de-aeration properties.
Are the DEFOAMER products stable at high and low pH values?
When DEFOAMER products are incorporated into a fluid concentrate; the pH value of said concentrate should be kept with the range of 6-11 to secure good, long-time stability. Use of DEFOAMERs as tank-side additive to diluted fluids is a very common application, and you can apply DEFOAMERs outside the 6-11 range. You will need to test the borderline in your system by practical testing.
