20090098300 | Coatings Comprisings Polysilazane for Preventing Scaling and Corrosion - A coating for surfaces, comprising at least one polysilazane of the formula 1 and/or of the formula 2 where n is an integer and is dimensioned such that the perhydropolysilazane has a number average molecular weight of 150 to 150 000 g/mol, a solvent and catalyst and, if appropriate, one or more cobinders, for preventing scaling and corrosion on metal surfaces. The hardened coating has a thickness of at least 0.2-10 micrometres, preferably 0.3 to 5 micrometres. It is particularly useful as a protective coating for metals for preventing scaling and corrosion. | 04-16-2009 |
20090220806 | Method for Improving the Corrosion Resistance and Lightfastness of Painted Aluminum Oxide Layers - Disclosed is a method for producing corrosion-resistant, painted oxide layers on aluminum or aluminum alloys. According to said method, a polysilazane solution is applied to a dry oxide layer that is painted with a water-soluble, anionic color, and the coating is then hardened at a temperature ranging from 40 to 150° C. | 09-03-2009 |
