Abstract
A method for producing an adhesive undercoat on a substrate S1 with a substrate temperature of lower than 5° C. The adhesive undercoat composition comprises at least one mercaptosilane MS or an adduct of mercaptosilane and either at least one polysilane PSA, comprising at least one secondary or tertiary amino group, or at least one polysilane PS and at least one aminosilane AS, comprising at least one secondary or tertiary amino group. This method is particularly suited for the gluing of glass, particularly of glass ceramics, preferably for repairing windows of motor vehicles in cold temperatures.
