    • The invention relates to coatings, with a contact angle hysteresis with water measured by the sessile drop method of at most 20°, which may 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 for coating, 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 R1of general formula (I): R1 = -CRa 2-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.
