Abstract

La duración en almacenamiento de una composición despumante a base de sílice es mejorada mediante la adición de resinas solubles en aceite y opcionalmente ácidos grasos alifáticos para retrasar la separación en inhibir la sedimentación. La composición es útil en la prevención de la espuma o en el despumado de sistemas acuosos como recubrimientos protectores al agua, adhesivos, agua negras y arrastre en monómeros.
