ELASTOSIL® LR 3671/40 A/B
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.
Eigenschaften
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® 3071/40 series the coefficient of friction of an article of ELASTOSIL® 3671/40 is reduced by 50 - 70 %.

Verpackung / Gebinde
This product is available in 20 kg pail and 200 kg drum kits.
Lagerung
Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
