Title:
ORGANOFUNCTIONAL SILOXANES, PROCESS FOR PREPARING SAME AND THEIR USE FOR THE TREATMENT OF FILLINGS AND SURFACES
Document Type and Number:
WIPO Patent Application WO/2019/180285
Kind Code:
A3
Abstract:
The present invention provides organofunctional siloxane, dipodal siloxane, siloxane block copolymer coupling agents, and a specific process for preparing these organofunctional siloxanes by an addition reaction of the hydride alkoxysilane and organofunctional disiloxanes to an organocyclosiloxane with a catalyst. The addition reaction according to the present invention does not produce a polymerisation and thus the new siloxane coupling agents are free from cyclosiloxanes and polymeric siloxanes. This makes them suitable for uses in adhesives, coatings and sealing agents. The present invention also relates to the use of these organofunctional siloxane compounds for the treatment of fillings and surfaces.
