Abstract

An admixture comprises an aqueous composition of a) a copolymeric dispersing component, b) an antifoaming agent component, c) a surfactant component, and d) water. The components may be a blend or physically or chemically attached and result in a stable liquid system that can be used as a dispersing agent for a calcium sulfate compound containing construction chemicals composition.

• C08F 28/02 - Homopolymers or copolymers of compounds having one or more unsaturated aliphatic radicals, each having only one carbon-to-carbon double bond, and at least one being terminated by a bond to sulfur or by a heterocyclic ring containing sulfur by a bond to sulfur
• C08F 22/10 - Esters

• C08K 5/10 - EstersEther-esters

Abstract

n>5000 g/mol are suitable as a mixture, in particular in construction chemistry applications, and in the development, exploitation and completion of underground mineral oil and natural gas deposits, and in deep wells, since they have excellent salt and temperature stabilities and are simultaneously water-soluble and/or biodegradable.
