摘要： Organosilicon compounds having at least one hydrocarbon radical linked to at least 75 percent of the silicon atoms via an oxygen atom in which the hydrocarbon radical has at least one hydroxyl group and may be linked again to the same silicon atom or to another silicon atom via an oxygen atom are added to room temperature curable organopolysiloxane compositions to form compositions which are resistant to flow on vertical surfaces. When these compositions are exposed to atmospheric moisture at room temperature, they form elastomers having decreased Shore hardness and modulus on the surface in contact with the substrate as compared to the surface exposed to atmospheric moisture.
