SEMICOSIL® 924

SEMICOSIL® 924 is a pourable,thermally curable, addition-curing one-part silicone rubber that cures to a very soft silicone gel.



特性

  •  one-part, ready-to-use
  •  thixotropic flow
  •  forms a soft gel on vulcanization
  •  low content of volatiles
  •  low content of uncured polymer
  •  low ion content
  •  almost constant properties between –50 °C and +180 °C
     

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。

Because of the thixotropic behavior, SEMICOSIL® 924 is specially recommended for local encapsulation of delicate electronic components, e.g. bonded chips on hybrid components which are exposed to extreme external influences.

Surface preparation
All surfaces must be clean and free of contaminants that will inhibit the cure of SEMICOSIL® 924. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds. If a substrate’s ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.


Dispensing
Because of the thixotropy (shear thinning effect) SEMICOSIL® 924 can be dispensed easily with all dispensing equipments.

To eliminate any air introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended.


Curing
SEMICOSIL® 924 works best when cured at 100 °C or more depending on the size and heat sink properties of the components.


The reactivity can be adjusted within wide limits by adding Catalyst EP or Inhibitor PT 88 to suit the processing requirements of the particular application. Catalyst EP increases the reactivity, i. e., pot life and curing time are reduced.
Inhibitor PT 88 is a pot life extender and prolongs pot life and curing time. Further information is given in our leaflet “Catalyst EP/Inhibitor PT88”.


We recommend running preliminary tests to optimize conditions for the particular application.
 

储存

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.
