MAPESIL FR

Neutral silicone sealant for fire-resistant joints

MAPESIL FR is a flexible silicone sealant used to create fire-resistant seals in walls, ceilings, plant system trays and passages in residential and industrial buildings and infrastructures.

In adverse weather conditions, MAPESIL FR behaves like a normal sealant to guarantee joints have a leak-proof seal to prevent water, air and dust from entering at temperatures from -40 to +180°C. In the event of fire, the particular formulation used to make MAPESIL FR forms a barrier to flames, smoke and heat passing through the sealed gap, thereby preventing fire propagating into adjacent rooms and environments.

ADVANTAGES:

High flexibility
Excellent resistance to bad weather and temperature variations
High bond strength with no primer on several substrates
Certified as resistant to fire, smoke and heat up to EI 240 minutes on walls, up to EI 180 on ceilings, without surface protection
Excellent flexibility and resistance to ageing
