Abstract: A mixture is proposed for treating substrates, in particular glass or ceramic material, containing silicon compounds. The proposed mixture consists of the following components: (a) component A, which is formed from at least the polysiloxane with Si--H bonds; (b) component B, which is formed from at least one bi-, tri- or tetrafunctional silane, an alkoxy or CH.sub.3 COO rest acting as the functional group; and (c) component C, which is formed from at least one strong, anhydrous organic or inorganic acid. The mixture can be applied to the substrate to particular advantage after being diluted with a solvent.

Abstract: Method for manufacturing a laminate consisting of at least two plates, which are attached to one another by means of an intermediate layer on the basis of a polymerizable resin, whereby a layer (7) of the polymerizable resin is applied on a horizontally placed plate (1) and whereby a second plate (9) is applied on this layer (7), after which the obtained whole is pressed together and the above-mentioned layer (7) is entirely polymerized, characterized in that between the application of the layer (7) and the application of the second plate (9), the layer (7) is first partly polymerized and this layer (7) is entirely polymerized after the whole has been pressed together.
