  • Patent number: 6599628
    Abstract: A primer composition of an organic titanate and an alkoxysilane achieves a strong bond between a silicone rubber and a fluoro-containing compound, thereby enabling a composite of these materials to have excellent adhesion. The composite is most useful as a fuser member in a copying device, the silicone rubber being upon an aluminum core. The primer composition preferably includes a solvent such as methyl isobutyl ketone that swells the silicone rubber, thereby permitting the primer composition to penetrate into the silicone rubber layer and further enhance the bond strength.

  • Publication number: 20020136903
    Abstract: This invention relates to a cross-linked polymer fuser member substrate that has been primed with a primer dissolved in a theta solvent. The substrate is contacted with the theta solvent in which the primer is dissolved. The solvent and the dissolved primer penetrate the cross-linked polymer network and cause it to swell. The solvent is removed such that the primer remains in the interstices and on the surface of the cross-linked polymer substrate.
