Abstract
An emulsifier composition comprising (a) a non-ionic emulsifier having an HLB-value of about 10 to 20 and (b) a polyoxyalkylene-polyester of which about 5 to 50% by weight comprises polyoxyalkylene radicals. It may be used in admixture with phosphoric acid esters, serving to reduce foaming and prevent settling of aqueous suspensions such as cement and calcium sulfate slurries.
Claims6
An emulsifier composition comprising by weight (a) about 5 to 30 parts of a non-ionic emulsifier having an HLB-value of about 10 to 20 and (b) about 10 to 40 parts of a polyoxyalkylene-polyester of which about 5 to 50% by weight comprises polyoxyalkylene radicals connected to the balance of the polyoxyalkylene-polyester molecules through urethane groups.
