LOW TEMPERATURE PLATINUM-VINYLPOLYSILOXANE HYDROSILYLATION CATALYST

摘要

Hydrosilation catalysts are provided in the form of platinum-MQ siloxanes. The platinum-MQ siloxane catalyst can be made directly from platinum-complexes containing at least one ligand and the desired MQ siloxane resin. The platinum-MQ siloxane catalyst can be employed as hydrosilation catalysts to make curable organopolysiloxane compositions.
