Abstract
Die Erfindung betrifft ein Verfahren zur Herstellung Fluoroalkyl-funktionalisierter hybridpolymerer Beschichtungen mit niedriger Oberflaechenenergie und geringer Verschmutzungsneigung. als Bestandteile der Beschichtungszusammensetzung dienen dabei organisch modifizierte Silane, Metallverbindungen der Formel AlR3 oder MR4 und zumindest teilweise fluorierte organisch modifizierte Silane.
EP 1197539 A UPAB: 20020829 NOVELTY - Preparation of coating compositions comprises hydrolytically condensing an organic modified silane, a metal compound and an organic modified silane. DETAILED DESCRIPTION - Preparation of coating compositions comprises hydrolytically condensing an organic modified silane of formula (I), a metal compound of formula (II) and/or (III) and an organic modified silane of formula (IV). R'mSiX(4-m) (I) AlR3 (II) MR4 (III) R'''mSiX(4-m) (IV) Where compound (II) and/or (III) is present from 5-75 mol.% of the mole total of the composition. X = H, halogen, alkoxy, acyloxy, alkylcarbonyl, alkoxycarbonyl or -NR''2; R'' = H, and/or alkyl; R', R''' = Alkyl, alkenyl, alkynyl, alkylaryl, aryl, arylalkyl, arylalkenyl, alkenylaryl, arylalkynyl, alkynylaryl, whereby such groups may be interrupted with an O, S or -NR'' group, and may be substituted with one or more groups selected from halogen, and optionally substituted amino, amido, aldehyde, keto, alkylcarbonyl, carboxy, mercapto, cyano, hydroxy, alkoxy, alkoxycarbonyl, sulfonic acid, phosphoric acid, (meth)acryloxy, epoxy, or vinyl group; m = 1, 2 or 3; M = Zirconium or titanium; and R = Halogen, alkyl, alkoxy, acyloxy, hydroxy or a chelating ligand. USE - As anti-adhesion coatings (claimed). ADVANTAGE - There is less tendency to soiling and the resistance to UV, abrasion, scratching and chemicals is good.
