ABSTRACT OF THE DISCLOSURE Difficultly wettable or non-wettable substrates, particularly substrates in the solid, gel-like or glass-like form, are rendered wettable in that at least one organo- metallic compound of an element of the fourth principal or secondary group of the periodic system of the elements, which serves as an active substance, causes an increase in energy of the substrate and is not soluble in the substrate, is added to the substrate in an amount causing an appreciable increase in energy and thus an increase of the surface tension of the substrate but no substantial change of the substrate structure and is homogeneously distributed in the substrate while form- ing finely divided punctiform aggregates whose particle size lies preferably in the range from 10-4 to 10-7cm. By means of this process substrates, particularly substrates which are subject to an intense mechanical stress, for example, vehicle tires as well as tool and machine parts, can be rendered wettable not only on the surface but throughout and thus permanently. Furthermore, with the aid of this process suspen- sions can also be stabilized permanently.
