FLOW-HP

POLYCARBOXYLATE BASED HYPER PLASTICIZER (POWDER)


Description:

The product gives the mortar excellent flow properties even if the water/cement (w/c) ratio is low. The quantity which needs to be added is considerably smaller than that of conventional plasticizers. We recommend  DOSTFLOW-HP for all cement systems in which the water requirement is to be reduced.


Application

Quantities of 0.2 – 0.4 %, in relation to the amount of binder used, produce the desired liquefying effect. The quantity added is dependent on various parameters (e. g. the quality of cement used) and must therefore be determined beforehand by means of preliminary tests. To reduce the air content of fresh mortar, we recommend formulating the product with 1 – 3 % of a standard commercial defoamer, e. g. Agitan®1 P 803  When developing formulations with DOSTFLOW-HP, producers should carry out their own careful tests since a large number of influences are involved in the manufacturing and processing of cement systems (e. g. compatibility with other ingredients, mixing procedures and water requirement) and we are unable to include them all in our own tests.
