Abstract

An aqueous polyorganosiloxane hybrid resin dispersion includes at least one polyorganosiloxane hybrid resin and at least one emulsifier based on partly hydrolysed polyvinylacetates. The dispersion has a solids content of 30.0% by weight-70.0% by weight, preferably 45.0% by weight-55.0% by weight, based on the polyorganosiloxane hybrid resin dispersion, and the residual solvent content is <6.0% by weight, preferably <2.5% by weight, more preferably <1.0% by weight, based on the polyorganosiloxane hybrid resin dispersion.
