WellFix FN

Antifreeze agent

Antifreeze complex agent for cement mortars WellFix FN is a product on the basis of salines of various molecular weight.

It is delivered in bags of 25 kg, on pallets of 1,000 kg.


WellFix FN is used in the process of well casing in winter conditions with the purpose of preventing freezing of cement mortars during their tempering and transportation. It also provides accelerated development of the initial strength of cement mortar under temperatures below 0°C. The WellFix FN additive improves rheological properties of cement slurry, thus, reducing the hydraulic resistance of cement mortar, and minimizing the pressure of pumping and squeezing when performing well cementing jobs.

Antifreeze agent WellFix FN has the following advantages:

  • It improves the plasticizing and tixotropic properties of cement slurry;
  • It increases water tightness;
  • It improves water regulation, decreasing water consumption by 7 to 13% and more, it’s frost-resistant, providing durability and hardening of cement slurries under temperatures down to minus 25°C.
