| Product description: Self-adhesive liquid silicone rubbers of the ELASTOSIL® LR 3071 series are paste-like, easily pigmentable two-component compounds with extremely short curing times. Special features: ELASTOSIL® LR 3071 series are primerless, self-bonding grades that adhere to various plastic substrates (e.g. PA, PBT) and metals, but not in the mold (adhesive adherence, protects against loss prior to assembly). The bonding is improved by an ageing process (e.g. one hour at 100 °C) or by a longer storing at room temperature. Because of the individual surface properties each substrate must be tested before mass production. If necessary one has to check the development of adhesive properties over time and/or in an environment relevant to the application. The vulcanizates are noted for good mechanical and electrical properties. Application: ELASTOSIL® LR 3070 series are particularly suitable for the economical production of large series of over molded parts (thermoplastic/elastomer), even in a comolding process (shuttle mold) under standard conditions, without any special treatment of the mold surface. Parts made from ELASTOSIL® LR 3070 can generally be used for technical applications without post-curing, but do not comply with regulations concerning use in the pharmaceutical and food industry.
