ABSTRACT:
Novel, curable polyurethane polymers in which a proportion of the NCO terminations are reacted with certain amino silanes, or with the residual on reaction of a mercaptosilane with a monoepoxide, or with the residual on reaction of an epoxysilane with a secondary amine.
Sealant compositions formed with the novel polymers are stable in storage, moisture curable and adhere well to various substrates, obviating the need for a primer.
