The invention relates to a multilayer material comprising (a) a first layer that consists of plaster or that substantially consists of plaster, and (b) at least one second layer, comprising a sandwich textile fiber material. The fibers of said material are interlinked in a mechanically stable manner, are incombustible and weather-proof and the interspaces are filled with a finely porous material. The second layer has a diffusion-equivalent air layer thickness of not more than 2.0 m and is water-impermeable at a water pressure of at least 100 mm water column. The inventive material can be used outdoors due to its properties. The invention further relates to methods for producing such a material.

Water-repellent and vapor-permeable multilayer material for outdoor applications

The present invention relates to an electrically conductive coating which is producible by hydrolytic condensation of a mixture including at least one hydrolysable silicon compound of general formula SiXR(I), wherein at least one of the R radicals is a mercapto-substituted alkyl or aryl group and is a compound of general formula ZSiYR(II), wherein the Z radical is for example a quaternary ammonium salt, whereby the mixture to be hydrolytically condensed comprises at least one portion of an ether containing and alkyl group. The coating is particularly suitable for toner transfer drums and has high scratch resistance and good adhesion to the substrate.
