    • A description is given of electrosterically stabilized polyurethane resins having an improved profile of properties, obtainable by a) preparing a hydrophilic and solvent-free macromonomer (A)(ii) with monomodal molecular mass distribution, by a1)reacting 50 to 100 parts by weight of a hydrophilic alkyl- or arylpolyalkylene glycol (A)(i) with 1 to 100 parts by weight of a polyisocyanate component (B)(i) optionally in the presence of a catalyst in the absence of solvents, and subsequently a2) reacting the uniform preadduct from stage a1) completely with 0.5 to 200 parts by weight of a compound (C) in the absence of solvents, and b) by preparing the polyurethane dispersion, by b1)reacting 2 to 50 parts by weight of the hydrophilic and solvent-free macromonomer (A)(ii) with 25 to 250 parts by weight of the polyisocyanate component (B)(i), optionally in the presence of 0 to 50 parts by weight of a solvent component (D) and also of a catalyst, b2) reacting the polyurethane preadduct from stage b1) with 50 to 100 parts by weight of a polymeric polyol (A)(iii) and optionally with 0.5 to 10 parts by weight of a low molecular mass polyol component (A)(iv), optionally in the presence of a catalyst, b3)reacting the homogeneous polyurethane preadduct from stage b2) with 2 to 20 parts by weight of a polyol component (A)(v), optionally in the presence of a catalyst, b4) admixing the homogeneous polyurethane prepolymer from stage b3), before or during dispersion in 50 to 1500 parts by weight of water, with 2 to 20 parts by weight of a neutralizing component (E), b5)dispersing the optionally (partially) neutralized polyurethane prepolymer from stage b4) in 50 to 1500 parts by weight of water, which optionally further contains 0 to 100 parts by weight of a formulating component (F), and finally b6)reacting the (partially) neutralized polyurethane prepolymer dispersion from stage b5) with 3 to 60 parts by weight of a chain extender component (G) and also, subsequently or simultaneously, with 0 to 30 parts by weight of a chain stopper component (H). The performance properties of the polyurethane dispersions of the invention in terms of absence of solvent, and also material properties, are excellent. Also deserving of emphasis are the simplicity and reproducibility of the process and the storage stability of the products.

    • A description is given of a fluorine-modified one- or two-component polyurethane resin having improved surface properties, which is obtainable by a) preparing a fluorine-modified polyurethane prepolymer having free isocyanate groups or free amino and/or hydroxyl groups, or a fluorine-modified polyol mixture having free hydroxyl groups (binder), and by b) preparing a fluorine-modified polyurethane resin having a polymer-bonded fluorine content of 1% to 4% by weight in the system as a whole by reacting the fluorine-modified polyurethane prepolymer from stage a3) in the case of a one-component application with atmospheric moisture, or reacting the fluorine-modified polyurethane prepolymer or polyol mixture (binder) in the case of a two-component application with a crosslinker component (D) (curing agent), with a formulating component (F)(ii) in the presence if desired of a solvent component (L)(iii) and also of a catalyst. Through the use of suitable fluorinated macromonomers in the one- or two-component polyurethane resins of the invention it is possible to produce hard coating systems and/or surfaces having very low surface tensions and very high contact angles. Furthermore, the dirt pickup tendency of these polyurethane resins is also significantly reduced as compared with the known prior art.
    • 对具有改善的表面性质的氟改性单组分或双组分聚氨酯树脂进行描述,其可通过以下步骤获得:a)制备具有游离异氰酸酯基或游离氨基和/或羟基的氟改性聚氨酯预聚物,或 具有游离羟基的氟改性多元醇混合物(粘合剂),以及b)通过使该氟改性多元醇混合物中的氟 - 在具有大气湿度的单组分施用的情况下,或者在双组分的情况下使氟改性的聚氨酯预聚物或多元醇混合物(粘合剂)反应,从阶段a 3阶段的改性聚氨酯预聚物) 在需要溶剂组分(L)(iii)和催化剂的情况下,用交联剂组分(D)(固化剂)与配制组分(F)(ii)的应用。 通过在本发明的单组分或双组分聚氨酯树脂中使用合适的氟化大分子单体,可以生产具有非常低的表面张力和非常高的接触角的硬涂层体系和/或表面。 此外,与已知的现有技术相比,这些聚氨酯树脂的污垢吸收趋势也显着降低。
