Getting started

Before use:

Working conditions

Only apply at temperatures between +5 °C and +40 °C.

Surface requirements

Ensure that joints are clean, dry and free of dust, rust and grease. Absorbent substrates and synthetics should be pre-treated with BISON Silicone Primer.

Preliminary surface treatment

For a good result, cover the joint’s edges with masking tape. If necessary, prevent three-sided bonding by filling the joint with a foam backer rod or PE film.


Apply cartridge with a Power Pistol. Multi Tool to open the cartridge and tooling the sealant.


Content suitable for approx. 8 to 15 m (depending on the diameter of the joint).

During use:

Handling of packaging

Use sealant gun to handle cartridge. Open the cartridge by cutting off the plastic nipple on the top side at the screw thread with a sharp knife. Screw on the nozzle and chamfer at the desired width.

Directions for use

Inject sealant evenly and slowly into the joint. Immediately smooth with a finger and soapy water. For bonding, join the parts within 5 minutes. After approx. 5 minutes, a surface skin will form. BISON High Temp reaches its high heat resistance after fully curing. The curing can be accelerated by heating the sealant to a maximum of 150 °C.

Points of attention

Silicone hardens under the influence of humidity. Contact with humidity is therefore absolutely necessary during curing.

After use:


Immediately remove stains with white spirit. Cured sealant can only be removed mechanically.

Storage conditions

Store in properly sealed packaging in a dry place at between +5 °C and +25 °C.
