Description
Product Details

A two-component, very soft, neutral silicone potting compound with very low viscosity and high transparency. In addition, the product has a very low shrinkage during curing (addition system), which combined with its very softness makes it suitable for sealing very delicate electronic systems sensitive to stress (e.g. pressure sensors).

Thanks to its self-adhesive surface quality, the compound adheres very well to various materials and the use of primers is not required.

The high softness after curing (consistency of non-flowing gel) and elasticity make it perfect for protecting electronic systems exposed to vibration (e.g. automotive electronics), overload or impact (protection of "black boxes").

All of the above features, together with a mixing ratio of 1:1 and identical density of both components (allowing for volumetric mixing, not weight-based like other potting compounds), make SilGel 612 A/B one of the most commonly used silicone potting compounds.

Thanks to its high flexibility, it is possible to locally remove the potting compound for repair purposes and then fill in the gap afterwards.
