Abstract
Described are compositions comprising a defoamer mixture comprising mineral oil and hydrophobic particles such as for example wax particles; di- or monoalkyl sulfosuccinate having at least 9 carbon atoms in the alkyl group and certain ethylene oxide/propylene oxide block copolymers. Also described are aqueous dispersions of hydrophobic polymers comprising these compositions and the use of the aqueous polymer dispersions as an adhesive, for example for producing composite films from transparent polymer films.
