METHOD OF ENVELOPING THE EDGES OF GLASS PANES WITH ELASTIC POLYISOCYANATE-POLYADDITION PRODUCTS

1. A process for enveloping the edges of a glass pane with a plastic using a mold, in which 1. the glass pane is inserted into the open mold, 2. the mold is closed, 3. the resulting free space between the glass pane and the mold is charged with a curable plastic and 4. the latter is cured, wherein t...

Beschreibung
Zusammenfassung:	1. A process for enveloping the edges of a glass pane with a plastic using a mold, in which 1. the glass pane is inserted into the open mold, 2. the mold is closed, 3. the resulting free space between the glass pane and the mold is charged with a curable plastic and 4. the latter is cured, wherein the curable plastic consists of a reactive mixture which contains a) organic polyisocyanates, b) relatively high molecular weight compounds having two or more reactive hydrogen atoms, selected from the group consisting of the polyether polyamines, polyether polyols, polyester polyols, polythioether polyols, polyester amides, hydroxyl-containing polyacetals and hydroxyl-containing aliphatic polycarbonates, or a mixture of two or more of the stated relatively high molecular weight compounds, c) chain extenders and/or crosslinking agents having a molecular weight of from 60 to 600 and a functionality of from 2 to 4, selected from the group consisting of the aliphatic, cycloaliphatic or araliphatic diols and/or triols, the secondary aromatic diamines, the primary, unsubstituted and/or substituted aromatic di- and/or polyvalent polyamines, and d) catalysts, with or without e) assistants and/or additives, and this mixture is injected into the free space between the glass pane and the mold by the reaction injection molding method and is allowed to cure to give polyurethane, polyurethane/polyurea or polyurea elastomers.
