    摘要: An adhesive coated mounting tape for flexographic printing plates for reducing the magnitude of the vibrations in the printing plate during its operation on a cylinder. The mounting tape comprises a strong reinforcing layer, e.g. a laminate of a polymeric film and a polymeric foam, which foam has a low value for resonant frequency before achieving vibration isolation, thus affording increased printing speeds and improved print quality.

    摘要: This invention provides for the radiation grafting of certain organopolysiloxanes to polymeric supports. The organopolysiloxane material is partially crosslinked mixture which contains from about 10% to about 90% by weight of uncrosslinked organopolysiloxane oil and has a cone penetration of about 100 to about 350 (10 -1 mm) and an ultimate elongation of at least about 100%. The organopolysiloxane fluid may be placed on the polymeric support and crosslinked to produce an organopolysiloxane material having the above properties and being bonded to the polymeric support. The organopolysiloxane material also can be crosslinked to the above properties by conventional means then placed in contact with the polymeric support and irradiated to crosslink the material to the polymeric support without substantially changing the properties of the organopolysiloxane material.

    摘要: A xylene-soluble, resinous copolymer containing SiO₂ units, trimethylsiloxane units, and alkenyldimethyl­siloxane units such as 5-hexenyldimethylsiloxane units is disclosed. The resinous copolymer is useful as a component in silicone coatings, especially silicone release coatings, to provide intermediate range release forces against adhesives. The higher alkenyl functionality provides faster reaction with other coating components and reduced odor during cure of UV curable mercaptosilicone compositions.

    摘要: The present invention relates to composite prelaminated closure systems, particularly to prelaminated tapes useful as diaper closures. A composite adhesive closure tape of the invention comprises an assembly of sheets laminated one over the other including a central elastomeric sheet having at least one stretching axis; anchor strips disposed over the elastomeric sheet and adhered to opposite marginal end portions of the elastomeric sheet, each anchor strip having one end portion adhered to the elastomeric sheet and an unadhered end portion extending along the stretching axis in opposite directions away from the elastomeric sheet, the unadhered end portions being covered on their bottom surfaces with adhesive; a release strip underlying the elastomeric sheet, the bottom of the release strip being at least partially covered with adhesive; and an attachment sheet underlying and adhered to a portion of one of the anchor strips and underlying end adhered to the adhesive of the release strip. The composite adhesive tape may be provided in a roll or attached to the edge of a diaper.
