Abstract

The sand is prepd. by adding expandable clays, esp. bentonites, and/or expanding fillers, such as starch, to up to 50% of the sand used, ad also adding 0.001-2.5% of a surfactant such as a polymerisate of gen-formula: where R is a fatty acid gp., and X is an oxyethylene gp. At least 20 oxyethylene gps are present in the molecule.
