ELASTOSIL 3671 series are primerless selfbonding grades that adhere to various thermoplasts (e.g. PA, PBT) and metals, but not to 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 storage 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. Compared to the ELASTOSIL 3071/50 series the coefficient of friction of an article of ELASTOSIL 3671/50 is reduced by 50 - 70 %.

Self-adhesive liquid silicone rubbers of the ELASTOSIL 3671 series are paste-like, easily- pigmentable two-component compounds with a very short curing time and good mechanical and electrical properties. Their vulcanizates are noted for their self-adhesive properties to various substrates combined with a low coefficient of friction.
