Black heat-resistant silicone in 20 kg drum, approved for drum press

Single-component acetic polymerization heatresistant silicone sealant which polymerizes at room temperature due to atmospheric humidity in order to grant a permanent and flexible bonding even at high temperatures (+250°C). Excellent adhesion even without primer on most non-porous siliceous materials such as glass, ceramic, glazed tiles and clinker, impregnated or painted wood and some type of plastics. The user should carry out some tests due to the variety of substances. The adhesion can be improved in many cases by using a primer on the substrates.

Applications

Mainly used to glue packings and tapes for stoves and fireplaces, to seal flanges of boilers, stoves, flues, heating system ducts and piping for transporting hot fluids; to replace gaskets on pumps, engines and machine tools; to glue or seal parts of electrical appliances. The silicone is not suitable for applications that require direct flame resistance.

Limits for use

Do not use on substrates such as marble, concrete, fibre-reinforced concrete and mortar, or in contact with metals such as lead, copper, brass or zinc because it causes corrosion. In contact with some organic elastomers (such as EPDM, APTK and neoprene), it may take on colour. Its use on natural stones like marble, granite and quartzite is not recommended because it may cause staining. It shouldn’t be used for gluing structural glazing. It is not suitable for head gaskets or for areas exposed to the flow of fuels.

User guide

The area of substrate in contact with the sealant should be clean, dry and without any kind of loose material, dust, dirt, rust, oil or other contaminants. Non-porous substrates should be cleaned with a solvent and a clean cotton cloth. Remove the residual solvent before it evaporates with a new dry cloth.

Storage

It has a duration of 18 months if kept in its original packaging in a dry and cool area away from direct light and at a temperature of between +5°C and +25°C. The product may still be usable even after the recommended storage period has passed.
