Patent number: 5653875Abstract: A structure comprising bodies having a functional surface property bonded to a substrate via a siloxane polymer adhesive. The structure may comprise a novel composition comprising a siloxane polymer having carbon bodies bonded thereto by direct carbon to silicon bonds. This composition may be used to bond carbon particles through a medium comprising the siloxane polymer to a vitreous, metal, plastic or other nucleophilic substrate. Alternatively, the bodies may comprise alumina, silicon, zeolite, organic polymers or other nucleophilic compositions, which are bonded directly to silicon atoms of the siloxane polymer. To bond carbon or other nucleophilic bodies to the substrate, the substrate is contacted with a mixture of the bodies and a hydrosiloxane polymer. The mixture is heated to cause the polymer to be bonded to the nucleophilic bodies, typically by C--Si, C--O--Si, Si--O--Si or Si--O--Al bonds, and to the substrate by reaction with the surface silanol or other nucleophilic groups.Type: GrantFiled: July 29, 1994Date of Patent: August 5, 1997Assignee: Supelco, Inc.Inventors: William R. Betz, James L. Desorcie

Patent number: 4954364Abstract: A method is provided for enhancing the controlled release characteristics of paper or plastic substrates by applying onto the substrate, a UV curable mixture of an epoxysilicone, an arylonium salt catalyst, such as a diaryliodoniumhexafluoroantimonate and a controlled release additive such as a phenolpropyl-substituted methyldisiloxane or an alkylphenol, such as dodecylphenol. The treated plastic or paper substrate is then subjected to UV irradiation to effect a tack-free cure of the UV curable mixture on the substrate.Type: GrantFiled: June 22, 1989Date of Patent: September 4, 1990Assignee: General Electric CompanyInventors: Judith Stein, Tracey M.
