Details
Silicone Fire Resistant is a silicone sealant designed for use in fire barrier systems. It has been specially formulated to withstand the high temperatures developed during a fire and to provide a perfect seal preventing the passage of smoke and fumes. These tests showed that joints sealed with Silicone Fire Resistant as described in the table on the next page prevent the passage of flame, smoke and gas and guarantee thermal insulation for up to 240 minutes (Class EI 240). Silicone Fire Resistant does not contain non-silicone plasticizers or flammable solvents. Neutral curing is caused by atmospheric humidity. It is neutral curing and does not therefore, produce unpleasant odours. It is composed of silicones only and therefore provides an excellent seal on porous substrates. In addition, Fire Resistant is certified as a non-structural joint sealant for façade elements, both indoors and outdoors, even in cold climates (F-EXT-INT-CC) according to EN 15651-1, and is certified by the GEV as EC 1 for its very low emission.
Instructions for use
Joint sizing: Certified joints must follow the geometry given in the official product classification reports.
- The joint flanks must be solid, clean and degreased. In the case of particularly critical substrates, the use of Primer Silicone pre-coating is recommended. Deep expansion joints must be buffered with suitable polyurethane foam preforms before sealing.
- Tape along the sides of the joint.
- Insert the cartridge into the cartridge gun, open it, screw on the nozzle and cut off the tip to obtain a sufficient opening.
- Inject plenty of sealant into the joint cavity.
- Smooth with a spatula moistened with Smooth within 5 minutes of application, exerting pressure to eliminate air pockets.
- Remove adhesive tape
Sealing can be done on both sides of the wall or only on the side not exposed to fire in the event of a fire (see tables on previous page). Certified joints must in any case follow the geometry given in the official product classification reports.
Storage
Store Silicone Fire Resistant in a cool, dry place. Stored in these conditions the product will keep for at least 12 months. Partly used cartridges can be stored for approx. 3 months provided they are tightly closed.

Silicone Fire Resistant is used for linear wall joints and fire doors. In areas where fire safety regulations must be met, it is used on mineral substrates with the same or higher density or thickness than in the test procedure. Silicone Fire Resistant adheres to a wide variety of substrates. It is composed of silicones only and therefore provides an excellent sealon porous substrates. Silicone Fire Resistant resists atmospheric agents and ultraviolet rays, in fact, years after installation, there are no traces of surface micro-cracks or chalking.
