What is it?
- Heat resistant upon complete curing up to 260 °C and briefly (approximately 1 hour) up to a maximum of 300 °C
- Easy to apply
- Not paintable
- Sealant may expand when it comes into contact with grease, oil, coolant and fuels.
What does it do?
Suitable for joining and sealing joints, seams and cracks in places where high heat resistance is required. Adheres very well to glass, enamel, tiles, glazed ceramics and smooth metals. Particularly suited for joining and sealing oven and microwave windows, edges around (ceramic) hot plates, heating ducts, flues, heat screens for the fireplace (also suitable in its fluid form for automotive applications).
Not suitable for:
Not suitable for applications where the product comes into direct contact with petrol, diesel fuel and jet fuel.
Only apply at temperatures between +5 °C and +40 °C.
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).
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.
Immediately remove stains with white spirit. Cured sealant can only be removed mechanically.
Store in properly sealed packaging in a dry place at between +5 °C and +25 °C.
