PREPARATION OF ISOCYANATE-TERMINATED POLYURETHANES CONTAINING AMINO SILANES |
摘要 |
<p>A process is disclosed in which polyalkoxy amino silane adhesion promoters are incorporated into isocyanate-functional polyurethane resins formed by the reaction of a stoichiometric excess of organic polyisocyanate with an hydroxy-functional resin without producing cloudy and/or unstable resin solutions. In this process, the hydroxy-functional resin is prereacted with the alkoxy functionality of the amino silane in a reaction which liberates alcohol, and then a stoichiometric excess of the organic polyisocyanate is added to cause the isocyanate groups of the polyisocyanate to react with both the hydroxy groups and the amino hydrogen atoms present.</p> |
