This silicone sealant resists heat up to 180 degrees, making it ideal for gaps and seams that can get hot. Waterproof and permanently elastic, so your repairs last a long time without discolouring.
When do you choose this product?
When do you need heat-resistant silicone sealant?
This UHU silicone sealant has been specially developed for situations where ordinary sealant falls short due to high temperatures. You use it for sealing and repairing joints, gaps and cracks in environments where heat plays a role. Think of connections around heating elements, hot water installations or other places where temperature fluctuations occur.
Why choose this black variant?
The black colour makes this sealant ideal for applications where you want a discreet, dark finish. Black silicone sealant is less conspicuous on dark surfaces and gives a professional appearance. The 80 ml content provides enough material for several small repairs or one larger job.
Heat resistance up to 180 degrees
Once fully cured, this sealant withstands temperatures up to a maximum of 180 degrees Celsius. This means your joints remain stable, even when considerable heat is generated. The sealant retains its elastic properties and does not discolour under the influence of temperature, ensuring durable results.
Waterproof and permanently elastic
The sealant is fully waterproof and remains permanently elastic after curing. This prevents the seal from cracking or coming loose due to movement or temperature changes. Please note that this is an acetic acid-based silicone – therefore ensure good ventilation during use and avoid contact with metals that are sensitive to acid.

Dex knows - user tips
Allow the sealant to cure fully before exposing it to heat or water; only then will it reach its maximum strength and heat resistance up to 180°C. Dispose of leftovers and the empty tube according to the rules for chemical waste in your municipality, as the substance is harmful to aquatic organisms.
