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。

ELASTOSIL® M 4440 is a general-purpose mold-making material suitable for casting resins, wax, gyp-sum, etc.


ELASTOSIL® M 4440 is preferred when no or only minor undercuts are involved and a certain inherent stability of the mold is required.

ELASTOSIL® M 4440 is cured by adding Catalyst T 37 for long pot lives and curing times, and Catalyst T 40 for short pot lives and curing times.


The pot life is the period of time at 23 °C / 50 % rel. humidity during which the catalyzed mix to attain a viscosity of 100,000 mPa s and still be just pourable

Comprehensive instructions are given in our leaflet “ROOM TEMPERATURE VULCANIZING (RTV) SILICONES - Material and Processing Guidelines"

Detailed information on other mold-making compounds in the ELASTOSIL ® M range is contained in our brochure “ELASTOSIL® Silicone Rubber for Mold Making”.
