| Empirical formula: C6H15NO5Si CAS No.: 23432-64-6 Properties: GENIOSIL® XL 63 is characterized by its high reactivity toward moisture, a direct consequence of the structural proximity of the nitrogen atom to the silicon atom (alpha-effect).On account of its highly reactive nature, GENIOSIL® XL 63 is of substantial importance in systems that cure very rapidly at room temperature on exposure to (atmospheric) moisture. This applies particularly to formulations in which alphaorganofunctional terminal groups function as crosslinkers. The addition of GENIOSIL® XL 63 greatly improves the storage stability. When they later cure, a very high degree of crosslinking is obtained via the trialkoxysilyl group. Special features: GENIOSIL® XL 63 is an alkoxysilane with an O-methyl carbamate organofunctional group. It´s a clear, colorless liquid with a characteristic odor. The silane hydrolyzes in the presence of moisture (methanol is released) to form silanols, which can then react with themselves to produce siloxanes. GENIOSIL® XL 63 is a highly reactive molecule capable of scavenging water in formulations. Application: GENIOSIL® XL 63 is used as a water scavenger in the production of moisture-curing adhesive and sealant formulations. It is important particularly in systems using highly reactive silane-modified polymers based on alpha-organofunctional silanes, since standard Information provided by Wacker Chemie AG. |
