Abstract
Branched polyglycols and branched polyether functional organopolysiloxanes are 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 well as coating compositions containing branched polyether functional organopolysiloxanes and a binder are disclosed. Coatings resulting from these compositions were more hydrophilic and had improved dirt release properties as compared to coatings containing similar, but un-branched, polyether functional organopolysiloxanes.
