Fluid-loss-control additive for high viscosity cement slurries ATREN CEM HV

Product description

High-viscosity filtration regulator for cement slurries. It is a water-soluble modified polysaccharide with high molecular weight.

Used to reduce the cement slurry filtration and prevent the subsidence of solid particles.

0.05–1% of dry cement weight as an anti-subsidence additive; 0.2–1% of dry cement weight as a filtration reducing additive 1–15 kg/m³.

Features

Can reduce the filtration of cement slurry of any density, but due to the fact that it increases the viscosity, it is more suitable for cement slurries with low density;
Significantly reduces shrinkage of the cement slurry;
Does not affect the cement slurry strength;
Environmentally friendly product, biodegradable without forming harmful substances;
Can be used in flush fluids as a thickener.
