  • Patent number: 10066396
    Abstract: A method of installing a roofing membrane includes providing a membrane including a polymeric body having first and second opposed planar surfaces and a lap edge, a pressure-sensitive adhesive layer disposed on the first planar surface, and a release member removably affixed to the adhesive layer. Then, cutting the release liner while simultaneously scoring the adhesive layer along a line substantially parallel to the lap edge by use of a cutting and scoring tool and said step of cutting and scoring includes contacting the tool to the release liner. Finally, removing the release liner to expose the adhesive layer in the lap area; then applying a high-tensile member to the exposed adhesive layer in the lap area and forcibly removing the high-tensile member to thereby remove the adhesive layer within the lap area; and seaming the membrane composite to an adjacent membrane.

  • Patent number: 5612141
    Abstract: An adhesive tape composition includes a polymer blend comprising at least one EPDM rubber, and preferably three EPDM rubbers in substantially equal amounts, and an adhesive-enhancing polymer selected from the group consisting of polyisoprene, polybutadiene, and ethylene-propylene copolymer and mixtures thereof. The tape adhesive composition further includes at least one tackifying additive compatible with said polymer blend and a sulfur and organic accelerator cure package for said polymer blend, the adhesive composition being devoid of butyl rubber which is found in most other adhesive tape compositions. This composition is seen as providing excellent long-term heat aging, weathering resistance, and low temperature properties as compared to adhesive tape compositions containing butyl rubber. Moreover, the adhesive tape composition provides more surface tack, better "quick-grab", and higher green strength as compared to adhesive tape compositions containing 100 percent EPDM rubber.

  • Patent number: 5407989
    Abstract: EPM and/or EPDM compositions exhibiting superior green strength as compared to conventional EPM/EPDM compositions are attained by adding, along with the rubber curing agents and various conventional additives as desired, colemanite and/or alumina trihydrate. Colemanite, alumina trihydrate or a mixture of the two have unexpectedly been found to enhance the green strength of EPM/EPDM compositions prior to vulcanization. The green strength promoters of this invention utilized in EPM/EPDM rubber compositions allows for faster mixing (shorter mixing cycles) and improved processing rates, such as faster calender throughput rates, to be achieved.

  • Patent number: 5204148
    Abstract: A laminate cover for sealing an opening in a weatherproof roofing membrane includes a top sheet of a weather resistant material, preferably an uncured butyl rubber EPDM material, and a complementary shaped and sized lower sheet of a lightly cured butyl rubber having opposed tacky surfaces. A layer of a flowable sealing material such as an uncured butyl rubber sealing compound having a smaller dimension than that of the lower sheet, is trapped between the lower sheet and a bottom release coated carrier. Upon removal of the carrier, the cover is pressed over the opening to be sealed and an exposed peripheral tacky area of the lower sheet secures the cover to the membrane and traps the sealing compound therein. Applied or ambient heat will cause the sealing compound to flow into the opening to effectively seal the same, and will vulcanize the top sheet to provide abrasion and weather resistance for the cover.

  • Patent number: 4419100
    Abstract: An ostomy appliance in which a pair of semi-rigid coupling rings and a flexible, resilient web are utilized for detachably connecting a collection pouch to a flexible faceplate. The appliance consists of two main parts: a pouch on which one of the coupling rings is mounted, and a faceplate to which the other of the rings is connected by means of the flexible annular web. The web allows limited floating action between the second coupling ring and the faceplate.

  • Patent number: 4378018
    Abstract: A male urinary drainage device composed of a thin resilient external catheter or sheath and an adhesive sealant pad for holding the sheath in place and for producing an effective seal to prevent urine backup and leakage. The pad is formed of compressible, deformable, water-resistant, and elastic sealant material and includes a ring portion adapted to seal about the penis at or directly behind the glans thereof and at least one integral strap portion projecting radially from the ring portion and intended to extend along the penile shaft. The strap portion functions primarily to provide sheath retention, whereas the ring portion coacts with the retained sheath and with the penis to serve primarily as a barrier against fluid backup.
