Scope of application

  • In aqueous interior paints;
  • In aqueous exterior paints;
  • Highly filled and highly pigmented watercolors;
  • In aqueous systems based on polyvinyl acetate, polyacrylic and styrene/acrylic homopolymer or copolymer;
  • In plasters;
  • In primers;
  • In sealants.


  • Compatible with most mineral fillers, pigments and aqueous dispersions;
  • It has a high degree of antifoam ability;
  • Improves storage stability of highly pigmented emulsion paints;
  • Does not distort the appearance of the surface;
  • It has high storage stability.


Defoamer ЕС70 can be added in the amount of 0.1-0.5% of the total mass of water dispersion paint.


It is recommended to introduce the defoamer ЕС70 in two stages: the first part before fillers and pigments are introduced into the system, the second part at the final stage of paint production.

Compatibility with other additives

Defoamer ЕС70 is compatible with most of the various additives used in watercolors


The composition of the paint and the dosage of the additive should be determined by laboratory tests.


Additive bulk can be supplied. Additionally, it is possible to supply in the following ways:
In 30 kg drum;
In 200 kg plastic barrel;
In 900 kg IBC in tank.

Storage and expiration date

It should be stored at temperatures between -10°С and +40°С. There may be slight decomposition during long-term storage, which does not affect the quality of the defoamer. To eliminate this, simply mix the defoamer. The expiration date is 12 months from the date of production in the original closed packaging under the specified storage conditions.

Security precautions

When applying the defoamer ЕС70, it is necessary to use protective clothing, gloves, glasses and masks and comply with industrial safety rules. Direct contact with eyes and skin should be avoided during storage and use. In case of swallowing, seek medical help immediately. It should be kept away from food.
