PROCESS FOR COVERING PANE GLASS EDGES USING ELASTIC POLYISOCYANATE POLYADDITION PRODUCTS Abstract of the Disclosure The invention is a process for coating with an adhesion-improving agent and covering the edges of plate glass, to be fitted to vehicle compartments, with poly- urethane, polyurethane-polyurea, or polyurea elastomers. The edges of the plate are coated with one or more layers of an adhesion-improving agent to achieve a good bond between the glass and the elastomer covering. A glass plate is positioned in a mold, the mold closed, and the cavity between the glass plate and mold filled with a reactable mixture of organic polyisocyantes, higher molecular weight compounds having at least two reactive hydrogen atoms, chain extenders and/or crosslinking agents, catalysts, and optionally auxiliaries and/or additives. The reaction mixture is allowed to cure and then the plate glass is removed.
