Abstract
A self-crosslinking polyurethane polymer hybrid dispersion based on oxidatively drying polyols having a high degree of film hardness is described, which is characterized in that it contains the reaction components claimed. The advantages of the polyurethane polymer hybrid dispersion according to the invention, such as a high degree of hardness in combination with high flexibility of the tear-free films, good resistance to chemicals, high stability of the dispersions in a wide pH range, good stability in the freezing and thawing cycle and the use of economical raw materials, are achieved in a simplified synthesis pathway wityout subsequent chemical crosslinking, and simultaneously with a low content of organic solvent (≦4% by weight) and good film formation at temperatures of ≧+10° C.
