Superplasticizing and super-water-reducing additive based on polymethylene-β-naphthalene sulfonates of optimized molecular weight distribution.

Kratasol-Extra is distinguished by a low content of sulfates. According to its consumer properties, Kratasol-Extra complies with the requirements of superplasticizing, super-hydrating additives.

Application area

The additive can be used when working with all types of oil well cement, as well as in lightweight, weighted, expanding, thermo-salt-resistant packings and special packing materials, in a wide range of temperatures and pressures.

Additive is not a corrosive component, does not cause corrosion of the equipment.


  • The universality of the additive - it combines well with slowing, accelerating, modifying components of different nature;
  • Stable plasticizing effect when working on cements of various mineralogical composition;
  • Reduces water demand;
  • It facilitates pumping out of solutions;
  • Does not contain chlorides.


The recommended dosage of the additive is 0.2-0.7% in terms of dry matter relative to the weight of the cement.

The optimum dosage of the additive is established during laboratory selection. It is recommended to dispense with an error of not more than ± 2%.

In liquid form, the additive is supplied in bulk in auto- and railway tanks, as well as in plastic containers of various capacities.

In dry form, the additive is packed in paper or polypropylene bags with a polyethylene liner or soft containers such as MKR (big bags).


Store at a temperature of +5 ÷ + 35 ° C in a closed container. Avoid exposure to direct sunlight. If the recommended storage conditions are violated, the physical, chemical and consumer properties of the product may change. Observance of the recommended conditions allows storing the additive within 12 months from the date of manufacture. In the case of the freezing of the aqueous solution of the additive after thawing and homogenization, the Kratasol-Extra superplasticizer can be used in accordance with the recommendations.

Precautionary measures

It is recommended to use protective gloves when working with the additive. If the additive gets on your skin, you should wash it off with soap and water. Avoid contact with eyes. In case of contact with eyes, rinse immediately with plenty of water and consult a doctor if necessary. Dispose of the additive according to local regulations, do not pour into the soil, water, sewerage.

Recommendations for the use of the additive are presented on the basis of the available practical experience, in compliance with the rules and recommendations for transportation and storage.
