<p>A composite structure comprising a substrate bearing a layer of release coating prepared from one or more epoxypolysiloxanes together providing cycloaliphatic epoxy group(s) and non-cycloaliphatic (i.e., linear or branched aliphatic) epoxy group(s). The resulting release coating cures quickly and exhibits low release levels to adhesive. An oligomeric epoxypolysiloxane comprising both cycloaliphatic and non-cycloaliphatic epoxy groups is also disclosed.</p> |
