20130005863 | DISPERSING AGENT - A preferably pulverulent dispersing agent comprising as the component having a dispersing action the combination of (a) at least one representative of polycarboxylate ethers with a weight content of from 0.1 to 20%, (b) at least one representative of polycarboxylate esters with a weight content of from 0 to 20% and (c) at least one representative of non-charged copolymers with a weight content of from 0.1 to 20%, which is accessible by co-spray drying the individual components and which is suitable for controlling the flowability of aqueous chemical construction suspensions is claimed. By the dispersing agents which form in situ according to the invention, a controllable subsequent dosing of dispersing agent can be achieved without an additional process step. Furthermore, by subsequent dosing with a flow agent, an increased dosing efficiency of a polymer can be achieved, the extent of the dispersing can be controlled in several stages and the duration of the processability of a fresh mortar can be prolonged especially at elevated temperatures by an increasing saponification. | 01-03-2013 |
