    Abstract: An iodine/iodide-containing hot melt coatable adhesive is provided. This adhesive is prepared by mixing iodine and an iodide salt, individually or in combination, with solubilizing liquids. The iodine and iodide salt are combined with a pre-adhesive composition in a hot melt mixer, with an iodine/iodide complexing agent being present in the mixture. The mixture is mixed at a temperature from about 130° C. to about 200° C. and sufficiently to form an iodine/iodide-containing hot melt coatable adhesive. Alternatively, the iodide may be generated in situ. The adhesive so prepared may be packaged for coating on a substrate at a later time, or may be immediately coated to form an adhesive composite. Adhesive composites, particularly surgical incise drapes, are provided incorporating this hot melt coatable adhesive.

  • Patent number: 7008985
    Abstract: An aerosol solvent weld cement composition for joining ends of plastic pipe. The composition contains at least one polymer capable of welding the plastic pipes to each other, at least one solvent for the polymer, and at least one propellant for the polymer/solvent solution. The composition is maintained under pressure greater than atmospheric pressure in an aerosol container. A female omnidirectional valve is disclosed for use in the aerosol container. This valve allows the solvent weld cement composition to be applied to pipes from any angle.

  • Patent number: 6797107
    Abstract: A solid cyanoacrylate adhesive composition is disclosed which can be applied to a substrate in solid form and which polymerizes into an adhesive polymer upon liquefying. Preferably the solid cyanoacrylate composition liquefies at temperatures slightly above room temperature and polymerizes upon liquification. &egr;-caprolactones are used as a solidifying polymer with cyanoacrylate monomers and other additives to form the solid cyanoacrylate adhesive composition. The solid cyanoacrylate adhesive composition is easy to apply, especially stable in solid form and is capable of use in a variety of industrial, consumer and medical applications.

  • Patent number: 6562181
    Abstract: A method for bonding together two substrates that includes applying to a first substrate an adhesive composition that includes (a) a trifunctional olefinic first monomer, (b) an olefinic second monomer that is copolymerizable with the first monomer and (c) a free radical initiator and then contacting a second substrate to the composition-applied first substrate so that the first and second substrate adhesively bond together. There is also provided a method for providing a coating on a substrate that includes applying to the substrate a composition that includes (a) a trifunctional olefinic first monomer, (b) an olefinic second monomer that is copolymerizable with the first monomer and (c) a free radical initiator and then allowing the composition to cure.
