Abstract
An aqueous polymer dispersion that includes a) a polyurethane dispersion having an average particle size of 60 to 350 nm and b) an aqueous silicon dioxide dispersion having a particle diameter of the SiOparticles of 20 to 400 nm. The dispersion is prepared by mixing the polyurethane dispersion (a) with the silicon dioxide dispersion (b). The aqueous polymer dispersion can be used in adhesive compositions, which can be used to bond substrates together, especially substrates that are structural components of shoes.
