ICA: B29C027-10; B29H008-00; B32B025-00. APPLICATION: JP 81-186569 19 Nov 1981. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Waterproof sheets are bonded with low-temp.-vulcanizable adhesive tapes of halogenated butyl rubber, silane coupling agents, and tackifiers. Thus, a tape (width 25 mm, thickness 1.0 mm) of brominated butyl rubber 100, 3-mercaptopropyltrimethyoxysilane (I) [4420-74-0] 2.4, Bu2Sn dilaurate (II), stearic acid 1, carbon black 50, CaCO3 20, CaO 20, acetone-4-tert-butylphenol copolymer [88190-71-0] 60, and paraffin oil 60 parts was placed between 2 sheets of vulcanized EPDM rubber (carbon black 70, CaCO3 20, ZnO 5, and process oil 20 phr with vulcanizing agents) and left 5 days at 50° nd 80% relative humidity to form a bonding having peel strength ~10 kg/25 mm, compared with ~1 kg/25 mm for a similar tape without I and II.
