  • Organofunctional siloxanes, process for preparing same and their use for the treatment of fillings and surfaces
    Patent number: 11773289
    Abstract: The present invention provides organofunctional siloxane coupling agents, dipodal siloxanes, siloxane block copolymers and a specific method for preparing these organofunctional siloxanes through an addition reaction of hydrido alkoxysilane and organofunctional disiloxanes to an organocyclosiloxane with a catalyst. The addition reaction of the current invention does not result in polymerization and therefore the novel siloxane couplings agents are free of cyclosiloxanes and polymeric siloxanes. This makes them apt for adhesives, coatings and sealant applications. The present invention also relates to the use of these organofunctional siloxane compounds for the treatment of fillers and surfaces.
