Drucsperse 1 – 45



Drucsperse 1 – 45 is a popular additive for ground treatment and dust stopping in mines. A dispersion agent for cohesive land, Drucsperse 1 – 45 is a high-performance liquid. It is formulated with special poly-carboxylates suited for the treatment of clay dispersion usually in the presence of strongly cohesive materials such as Benton slurries, kaolin, etc.

One of the key characteristics of Drucsperse 1 – 45 is that it is not affected by hardness and thermal excursions.

It should ideally be stored at temperatures ranging from 5 to 50° C.


  • Dispersion /breaking up of highly cohesive clayey land with a consequent decrease in viscosity, during TBM excavation
  • Dispersion, breaking up and stabilisation of fine compact and cohesive land in general (bentonite, kaolin, ).
  • Facilitate the resumption of excavations with milling cutters after long

(at + 20° C)
