Title
(DE) ISOCYANATFREIE KETTVERLÄNGERUNG UND VERNETZUNG MITTELS FUNKTIONELLER SILANE
(EN) ISOCYANATE-FREE CHAIN EXTENSION AND CROSSLINKING USING FUNCTIONAL SILANES
(FR) EXTENSION DE CHAÎNE SANS ISOCYANATE ET RÉTICULATION AU MOYEN DES SILANES FONCTIONNELS
Abstract
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung von polymeren, Organosilanhaltigen Verbindungen durch Umsetzung isocyanatreaktiver Verbindungen (P) mit speziellen Silan-Verbindung (S), die daraus erhältlichen Polymer-Verbindungen, sowie deren Verwendung in der Herstellung ungeschäumter Polymere, von Weichschäumen und/oder Zwei-Komponenten (2K)-Systeme sowie deren Verwendung in CASE-Bereich (Beschichtungen, Klebstoffe, Dichtungen und Elastomere), Möbeln, Matratzen, Autositzen, Dichtungs- oder Akustikmaterialien, zur Isolation von Fernwärmerohren, Tanks und Pipelines sowie zur Herstellung aller Arten von Kühlvorrichtungen.
