BRANCHED POLYGLYCOLS AND BRANCHED POLYETHER FUNCTIONAL ORGANOPOLYSILOXANES AND COATINGS CONTAINING SAME

摘要

Branched polyglycols and branched polyether functional organopolysiloxanes a re disclosed as is a process for making branched polyether functional organopolysiloxanes by reacting an organohydrogensiloxane and a branched polyglycol having an unsaturated group via a hydrosilylation reaction, as we ll as coating compositions containing branched polyether functional organopolysiloxanes and a binder are disclosed. Coatings resulting from thes e compositions were more hydrophilic and had improved dirt release properties as compared to coatings containing similar, but un-branched, polyether function al organopolysiloxanes.
