MS149

主银149是2的部分光学透明，灵活的冷凝固化液体硅其中，后固化剂149此外，在室温下固化到一个艰难的，有弹性的硅橡胶灌封和封装化合物。 主银149用于灌封和电压调节器，高​​压变压器，以及光学和电子组件封装。 它的“机械和电气性能独特的混合提供保护敏感的电子元件和灰尘，潮湿，臭氧，热冲击和振动组件。 缩合固化有机硅不建议是完全密封之前，完全固化的应用程序。 一个“逃跑”路径是必需的，以便在混合的过程，以促进形成固化周期完成非危险biproducts释放。

Master Sil 149 is a 2 part optically clear, flexible condensation cured liquid silicone which, after the addition of curing agent 149, cures at room temperature to a tough, resilient silicone rubber potting and encapsulation compound. Master Sil 149 is used for potting and encapsulation of voltage regulators, high voltage transformers, as well as optical and electronic assemblies. Its’ unique blend of mechanical and electrical properties offer protection to sensitive electronic components and assemblies from dust, moisture, ozone, thermal shock and vibration. Condensation cured silicones are not recommended for applications which are completely sealed prior to full cure. An “escape” path is required to allow for the release of non-hazardous biproducts formed during the mixing process which promotes completion of the curing cycle.
