Abstract:
1. A polymer mixture for decorative surfaces in an automobile interior, comprising: 0.1%-50% by weight of a first aqueous polymer dispersion of a first polymer selected from the group consisting of a polyurethane, a polyester, a polyether, a polyester-polyacrylate, a polyacrylate-polyurethane, and a polyacrylate, or a mixture thereof, 1% -60% by weight of a second aqueous polymer dispersion of a second polymer selected from the group consisting of a polyurethane, a polyesterpolyol, and a polyetherpolyol, or a mixture thereof, the second polymer being functionalized with OH groups and/or NH groups and possessing an OH content or NH content of between 0.3% and 6.0% by weight, based on the nonvolatile fraction of the total amount of the second aqueous polymer dispersion; 0.1%-40% by weight of polydimethylsiloxane; 1%-40% by weight of a modified polysiloxane slip additive; 0.2%-50% by weight of at least one crosslinker or crosslinker system; 0.1% -75% by weight of at least one matting agent; 0%-50% by weight of a diluent; 0%-50% by weight of other adjuvants, based on the nonvolatile fraction of the total amount of polymer mixture, wherein the modified polysiloxane slip additive has an amine number of between 0.1 and 3.0 mg KOH/g and/or an OH content of between 0.3% and 5.0% by weight.
