The invention relates polysilazane-containing coatings for increasing the light permeability of sun-facing covers of solar cells. The coating for surfaces contains at least one polysilazane of formula (1) &#x2014;(SiRR'R&#x2033;&#x2014;NR&#x2032;&#x2033;1)n- (1), wherein R&#x2032;, R&#x2033;, R&#x2032;&#x2033; are the same or different or represent an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group, n being an integer and n being chosen in such a manner that the perhydropolysilazane has a number average molecular weight of 150 to 150,000 g/mol, a solvent and a catalyst. The cured coating has a thickness of at least 0.50-10 micrometer, preferably 0.2 to 5 micrometer, especially preferred 0.5 to 1.5 micrometer. It is especially suitable as transmission-promoting coating for use in sun-facing covers of solar cells.

Polysilazane-containing coatings for increasing the conversion efficiency of encapsulated solar cells

The present invention is directed to a color-pigmented paint composition with high hiding power, comprising a solvent or a solvent mixture and

Color-pigmented paint composition having high covering powder, increased scratch resistance, and easy-to clean properties

The invention relates to the use of polysilazanes as a permanent coating on metal and polymer surfaces for preventing corrosion, increasing scratch resistance and to facilitate easier cleaning. The invention comprises a solution of a polysilazane or a blend of polysilazanes of the general formula 1&#x2014;(SiR'R&#x2033;&#x2014;NR&#x2032;&#x2033;)&#x2014;&#x2003;&#x2003;(1)where R&#x2032;, R&#x2033; and R&#x2032;&#x2033; are identical or different and independently of one another represent hydrogen or an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group and n represents a whole number and is calculated in such a way that the polysilazane has a numerical average molecular weight of 150 to 150 000 g/mol, in a solvent. The invention also relates to a method for producing the coating.

Coatings containing polysilazanes for metal and polymer surfaces

A coating for metals containing a polysilazane solution or a mixture of polysilazanes of the general formula (I)&#x2014;(SiR'R&#x2033;-NR&#x2032;&#x2033;)&#x2014;&#x2003;&#x2003;(1)

Use of polysilazanes for coating metal strips

A coating for surfaces, comprising at least one of the polysilazanes having the formula 1 and/or 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 a catalyst and, if desired, one or more cobinders, for preventing scaling and corrosion on metal surfaces. The hardened coating has a thickness of 0.2-10 micrometers, preferably 0.3 to 5 micrometers. It is particularly useful as a protective coating for metals for preventing scaling and corrosion.

Coatings comprising polysilazanes for preventing scaling and corrosion

A method for producing corrosion-resistant, painted oxide layers on aluminum or aluminum alloys. According to the 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&#xb0; C.
