High Temperature Silicone Sealant Heat Resistant to 1500°C, Flues, Stoves, Glass

Silicate based sealant for high temperature applications. Insulation and filling of cracks. As the result of heating, the mass will turn dark grey, extra hard and withstands temperatures of up to 1500ᵒC. Suitable on natural stones. Insulation of joints and filling of cracks in chimneys, ovens, fireplace and stoves. Adheres to metal, stone, brick and concrete. Exercise care during any contact with metal which deforms when exposed to high temperature as opposed to the sealant itself.

Odourless and ready to use, this flexible, halogen free silicone sealant is heat resistant to 1500ᵒC and reacts with atmospheric moisture to form a durable flexible seal. Ideal for high temp applications such as sealing connections between single skin flue pipes and can be used outside on the Flashing.

The surfaces must be clean from dust, loose particles and oil. Non-porous surfaces should be cleaned with solvent and a clean, non-fluffy cotton cloth. Solvent rests should be removed before evaporating with the clean cloth. Very porous surfaces should be previously slightly moistened.

310 ml cartridge: cut off the threaded end of the cartridge and screw on the application nozzle for directing sealant. Cut the threaded end in a way where a suitable opening for application is produced. Place the cartridge together with the applicator in the gun and fill the installation nozzle with sealant, by repeatedly pressing the gun trigger.

Apply sealant in the joint by repeatedly and evenly pressing on gun trigger and smoothly dragging the nozzle along the joint. After application, smooth the surface with a rubber silicone scraper or putty knife and remove excess material. In some cases, it is more convenient to use plaster spatula.

Not suitable in moving joints and in contact with materials that expand or contract when exposed to temperature. Unheated product is not waterproof and will spread in a wide joint.
