Selected properties of our RTV-2 silicone gels

Viscosity

The viscosity and flow behaviour are of particular importance when processing the gels. Thanks to the gels’ excellent flow properties, air pockets are prevented and components are coated optimally. As their viscosity remains consistent across different shear rates, the gels are very well suited to automated production.

Adhesion

Gels adhere very well to the housing due to their residual tack, thereby providing good protection that is maintained across a wide temperature range. The Tough Gel is an exception to this; whilst it does not adhere, it offers higher mechanical properties.

End state

Gels are under cross-linked potting materials; this results in residual stickiness on the surface, but also in low mechanical properties. This is required for applications across a wide temperature range. Gels are so soft that they absorb the forces generated by thermal expansion, thereby protecting the components. Their hardness is often only a few Shore 00.
