Abstract: The invention relates to coatings with a contact angle hysteresis in water as measured by the tilting plate method of at most 20° made from silyl-terminated linear prepolymers which may cross-link with the surface of the substrate for coating, wherein the silyl-terminated linear prepolymers may be obtained by reaction of compounds of general formula (I): X-A-X′ (I), where A=a polyoxyalkylene chain of ethylene oxide units or ethylene oxide and propylene oxide units with a maximum fraction of 50 wt. % of propylene oxide units based on the weight of A, X═OH, NH2, NHR, NR2 or OR, wherein R independently=a linear or branched 1-10 C alkyl, a 6-10 C alkaryl or aralkyl or a 5-10 C aryl and the compound of general formula (I) has a number average molecular weight of at least 100 g/mol, with compounds of general formula (II) Y—B—Si(OR1)r(R2)3−r, where Y=a group reactive with OH, NH2, NHR and/or NR2, B=a chemical bond or a divalent low-molecular weight organic group with preferably 1-50 carbon atoms, OR1=a hydrolysable group, R2=a linear or branched 1-6C alkyl and r=a number from 1 to 3 and optionally unreacted hydrogen atoms on the group X and/or the group X′ are optionally alkylated. The invention further relates to the production of such coatings and the use of the silyl-terminated linear pre-polymers from production of such coatings and application in mixtures with stellate silylated prepolymers.
