ABSTRACT:
Thickening agents contain polyether derivatives and low-molecular-weight alkylene glycol alkyl ethers, further common additives as required, and water as the rest, up to 100%. Mono-, di- or trialkylene glycol alkyl ethers are preferred. It is possible to prepare stock solutions with thickener concentrations of 50% and more. The thickening agents, because of their unexpectedly low viscosity, can be handled very well, and they exhibit synergistic effects during thickening, especially of aqueous systems.
