57 Abstract AB [DE] Beschrieben wird eine feste, aufschmelzbare und thermisch härtbare Masse, umfassend Kondensate K, die von mindestens einem hydrolysierbaren Silan und gegebenenfalls einer oder mehreren hydrolysierbaren Metallverbindungen abgeleitet sind, wobei sich an Zentralatomen M der Kondensate K Gruppen A befinden, die eine Weiterkondensation der Kondensate ermöglichen, mindestens 70% der Zentralatome M eine oder mehrere daran gebundene, nicht hydrolysierbare organische Gruppen R aufweisen, von denen ein Teil durch mit den Zentralatomen M koordinierte komplexbildende Spezies ersetzt sein kann, und die Kondensate K im Temperaturbereich von 50 bis 200 DEG C ein Viskositätsminimum im Bereich von 10 mPa.s bis 150 Pa.s durchlaufen. Diese Masse eignet sich z. B. zur Verwendung in einem Pulverlack zur Beschichtung von Substraten aus Metall, Kunststoff, Glas und Keramik.
[EN] Fusible and heat-curable solid materials based on condensates with a viscosity minimum of 10 mPa.s to 150 Pa.s in the range 50-200 deg C, derived from hydrolysable silanes (and possibly also hydrolysable metal compounds) containing groups which enable further condensation and also non-hydrolysable organic groups. Fusible and heat-curable solid materials comprise condensates (K) derived from hydrolysable silane(s) and optionally hydrolysable metal compound(s), with central atoms (M) linked to groups (A) which facilitate further condensation of (K) and with non-hydrolysable organic groups (R) on at least 70% of the atoms (M), these groups (R) being partly replaceable by complex-forming species coordinated with (M). The viscosity of (K) passes through a minimum value of 10 mPa.s to 150 Pa.s in the range 50-200 deg C. Independent claims are also included for (a) a process for coating substrates with coating powder based on these materials; (b) a process for the production of these materials by controlled hydrolytic condensation of hydrolysable silicon compounds and/or corresponding silanols with some non-hydrolysable groups (R), optionally with hydrolysable metal compounds, to give condensates with the above viscosity characteristics, followed by removal of any volatiles.
