摘要： Embodiments of the present application relate to a composition including A) at least one aminosilane which has at least one hydrolyzable group bonded to Si, B) at least one mercaptosilane which has at least one hydrolyzable group bonded to Si, and C) at least one emulsifier selected from pyrrolidones, propionamides and amino alcohol reaction products, wherein, if at least one amino alcohol reaction product is used as an emulsifier, an amino alcohol and at least part of the aminosilane and/or mercaptosilane are contained in the form of an amino alcohol reaction product, in which at least some of the hydrolyzable groups present in the at least one aminosilane and the at least one mercaptosilane are replaced by the amino alcoholate group of the amino alcohol, D) and/or hydrolysis and/or condensation products of the silanes contained.
