Abstract
An alkoxysilane functionalized polysiloxane polymer can be prepared from a mixture of reactants including: a) a polysiloxane polymer having two or more reactive functional groups selected from -A-NH2, -A-OH, -A-N═C═O, -A-COOH, or combinations thereof; and b) at least one alkoxysilane having a functional group that is reactive with the reactive functional groups on the polysiloxane polymer. The alkoxysilane functionalized polysiloxane polymer can be combined with additional components to form a coating composition.
