免责声明

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。

The bonding is improved by an ageing process (e. g. one hour at 100 °C) or by longer storing at room temperature. The individual surface properties each substrate must be tested before mass production. If necessary, check the development of adhesive properties over time and/or in an environment relevant to the application. ELASTOSIL® LR 3071/40 A&B US is noted for its’ ability to be molded into intricately-shaped, precision parts.  Very brief molding cycles for intricately-shaped and flash-free parts are possible.

 

  • Food contact applications:
    • FDA 21CFR177.2600
    • BfR Recommendation XV, Silicones
  • Soft-Touch handles and buttons

ELASTOSIL® LR 3071/40 US A/B can be processed using standard liquid rubber injection molding techniques.


Vulcanization

ELASTOSIL® LR 3071/40 US A/B is vulcanized by mixing part A with part B in a ratio of 1:1 with the application of heat.  Mold temperatures are usually in the range of 160 °C (320 °F) to 210 °C (410 °F).  Actual mold temperature and cycle times will be dependent upon a number of factors.  Cycles times may be as little as 20 seconds for small parts.

包装

ELASTOSIL® LR 3071/40 US A/B is available in 40 kg. (88 lb.) pail kits and 380 kg (838 lb.) drum kits.

储存

ELASTOSIL® LR 3071/40 US A/B has a shelf life of at least 3 months when stored below 32 °C (90 °F) in the tightly closed original container. 

 

Storage beyond the recommended shelf-life does not necessarily mean that the product is no longer usable. However, the properties required for the intended use must be checked for quality assurance reasons.

 

Once opened, containers should always be resealed to prevent catalyst poisoning by amines, sulfur compounds, and other substances.
