EC name

Spolostan 7G is a highly efficient superplasticizer for concrete and mortar mixtures.

Using Spolostan 7G in a concrete mixture at given proportions of cement, sand and aggregates provides for achieving enhanced workability (increased flow) of fresh concrete, increased concrete strength in first days and months (by 15 – 50 %) by reducing the amount of mix water while retaining its workability and achieving cement savings up to 20 % while retaining the concrete strength.

Spolostan 7G is used especially for massive and reinforced concrete structures, precast concrete elements and structures as well as concrete for hydraulic structures.

Spolostan 7G is also employed in oil field chemicals for oil well cementing or as a dispersing agent in emulsion polymerization.
