ELASTOSIL® LR 3071/40 F A/B

Self-adhesive liquid silicone rubbers of the ELASTOSIL® LR 3071 F series are paste-like, easily-pigmentable two-component compounds with extremely short curing times. Their vulcanizates are noted for excellent mechanical and electrical properties.



特性

ELASTOSIL® LR 3071 F series are primerless selfbonding grades that adhere to various thermoplasts (e.g. PA, PBT) and metals. 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.

所提供之所有信息均基于我们当前所掌握的知识。尽管如此,我们不对其作任何担保、也不承担任何责任,并且保留在任何时候进行技术变更的权利。购买方应在预测试中对所提供之信息以及产品在既定应用中的适应性进行检查。任何时候都必须以合同条款与条件为准。此外,本免责申明还适用于与第三方权利有关之事宜,尤其是在德国境外。

ELASTOSIL® LR 3071/40 F A/B is particularly suitable for the economical production of large series of overmolded parts (thermoplastic/elastomer), even in a comolding process (shuttle mold) under standard conditions, without any special treatment of the mold surface.

Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances. In addition, the siloxane based starting substances are listed in Table A.2 of the Chinese standard GB 4806.11-2016 and the contained additives are listed in Table A.3 or A.7 of the standard GB 9685-2016 for rubber or silicone rubber, respectively.

The A and B components are delivered ready to use in 20 kg pail and 200 kg drum kits. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by astatic mixer. The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least threedays. Note: Start-up of new molds should be supported by use of ELASTOSIL® AUX Mold Release Agent 32. For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".

包装

This product is available in 20 kg pail and 200 kg drum kits.

储存

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.
