    • The invention relates to coatings having a contact angle hysteresis with water measured by the sessile drop method of at most 20°. The coatings can be produced from a mixture of at least two different stellate prepolymers and/or stellate prepolymer/nanoparticle complexes which may cross-link to each other and to the surface of the substrate coated, wherein the stellate prepolymers and/or stellate prepolymer/nanoparticle complex have at least three hydrophilic polymer branches before cross-linking which are themselves soluble in water with on all or a part of the free ends thereof, silyl end groups R1 of general formula (I): R1=—CRa2—Si(ORb)r(Rc)3−r, where Ra=H or straight or branched chain 1-6C alkyl, ORb=a hydrolysable group, Rc=linear or branched chain 1-6C alkyl and r=a number from 1 to 3 and the optionally non silyl end group carrying ends have reactive end groups which a reactive with each other, with the substrate to be coated optional entities included in the coating and/or with the silyl end groups with the proviso the mixture (a) has at least one stellate prepolymer with 3-5 hydrophilic polymer branches and (b) at least one stellate prepolymer and/or a stellate prepolymer/nanoparticle complex with a least 6 hydrophilic polymer branches. The invention further relates to a method for production for said coatings and stellate prepolymers as used in the coatings. The invention furthermore relates to the use of the stellate prepolymers as additives in various materials for temporary or permanent anti-soiling treatment of surfaces.
    • 本发明涉及具有至多20°的无固定滴落法测量的与水接触角滞后的涂层。 涂层可以由至少两种不同的星状预聚物和/或星状预聚物/纳米颗粒络合物的混合物制备,所述星状预聚物和/或星状预聚物/纳米颗粒复合物可以彼此交联并与涂覆的基材的表面交联,其中星状预聚物和/或星状预聚物/ 纳米颗粒络合物在交联之前具有至少三个亲水性聚合物分支,其自身可以在其全部或部分自由端上溶解在水中,通式(I)的甲硅烷基端基R1:R1 = -CRa2-Si(ORb )r(Rc)3-r,其中R a = H或直链或支链1-6C烷基,ORb =可水解基团,Rc =直链或支链1-6C烷基,r = 1至3的数, 任选的非甲硅烷基端基的端部具有彼此反应的反应性端基,待涂覆的底物包含在涂层中的任选实体和/或甲硅烷基端基,条件是混合物(a)具有至少一个 星状预聚物与3-5亲水聚合物麸 c)和(b)至少一种具有至少6个亲水性聚合物分支的星状预聚物和/或星状预聚物/纳米颗粒络合物。 本发明还涉及用于涂料中的所述涂料和星状预聚物的生产方法。 本发明还涉及星状预聚物作为各种材料中的添加剂用于表面的临时或永久性防污处理的用途。
