Crystalgel is a re-enterable transparent two-component silicone gel for insulated filling and sealing of casings and junction boxes housing electrical connections of up to 1 kV or electronic components, suitable for a wide range of applications.

Crystal clear

Crystalgel is extremely transparent, which means that the contents of the casing are always visible.

Easy and without waste

The two components supplied in separate containers always guarantee the correct 1:1 mixing ratio. Crystalgel is supplied with a new 1 liter jug, which allows to mix the entire contents of the bottles in one go, making installation even faster. Crystalgel may be partially used as needed, and reused even after the pack has been opened, providing maximum yield.

High performance

High dielectric strength: 24.5 kV/mm. Wide range of operating temperatures: -60 to 200° C.

Re-enterable and removable

Once cross-linked, Crystalgel can easily be removed without the need for tools even after long periods of time.

Low viscosity

Its low viscosity makes Crystalgel easy to pour and ensures fast and safe filling of the containers and gaps.


Crystalgel is non-toxic, non-irritating, odourless, and solvent-free, and is classified as non-hazardous under European Regulation no. 1272/2008 (CLP).
