Quartz Or Glass Patents (Class 428/425.6)
  • Patent number: 6270902
    Abstract: A two step method or process for improving the adherence or bonding of a lubricious coating of a crosslinked polyurethane, polyurea or polyurethaneurea/PEO or PVP coating to a substrate surface, said two step method comprising a first step of subjecting said surface to a surface preparation which results in the treated surface being provided with a functional tie layer containing functional groups for reaction with functional groups of a reaction mixture to be applied in a subsequent second step, which upon curing forms a crosslinked polyurethane, polyurea or polyurethaneurea/PEO or PVP coating and a second step of applying to said tie layer said reaction mixture and curing the reaction mixture. A medical device resulting from the above-described two step method.

  • Patent number: 6265054
    Abstract: The invention relates to a composite glazing material of the type including two sheets of glass and an interlayer of transparent plastic of greater thickness than the thickness of the sheets of glass, characterized in that the plastic is capable of adhering to the glass. The glazing material has a total thickness smaller than 5 mm, a ratio of the thickness of the interlayer to the thickness of the sheets of glass of between 1 and 10, a mass per unit area lower than 6 kg/m2 and a Young's modulus higher than 30 GPa at a total thickness of glazing material of 3 mm.

  • Patent number: 6248127
    Abstract: Coatings are provided in which biopolymers may be covalently linked to a substrate. Such biopolymers include those that impart thromboresistance and/or biocompatibility to the substrate, which may be a medical device. Coatings disclosed herein include those that permit coating of a medical device in a single layer, including coatings that permit applying the single layer without a primer. Suitable biopolymers include heparin complexes, and linkage may be provided by a silane having isocyanate functionality.

  • Patent number: 6203914
    Abstract: An ink-fouling preventing sheet which is attached to a feed or delivery cylinder that supports and moves a printed paper in an offset press. The sheet comprises a flexible sheet base; an adhesive layer formed on the base; many small balls partially buried in the adhesive layer; a primer layer applied over the exposed convex portions of the small balls in the adhesive layer; and a set resin layer made of a silicone-modified urethane resin and applied on the primer layer to take the convex shapes of the small balls.
