FIRESTOP Sealant

Fire-rated one-part silicone sealant for interior and exterior linear joints and penetration seals
 
Features & Benefits:
• Cures at room temperature when exposed to moisture in air
• Neutral cure, halogen-free
• Easy to apply: non-slump
• Excellent unprimed adhesion to most porous and non-porous construction substrates
• Excellent weathering characteristics, including resistance to ozone, UV radiation and temperature extremes
• Joint movement capability ±50% (ISO 9047)
• Tack-free in 1.5 hours
• Fire reaction tested and classified B,s2,d0 according to EN13501-1
• Fire resistance tested for linear joints according to EN1366-4 and BS 476 Part 22
• Fire resistance tested for penetration seals according to BS 476-22
• A fire resistance rating in integrity (E) and insulation (EI) of up to 240 minutes–4 hours
• can be achieved depending on the joint configuration
 
Applications:
 The sealing of vertical and horizontal linear expansion joints and pipe and cable penetrations in fire rated walls 

 
Instructions:
• The joints must be clean and free from dust, grease and rust.
• No primer is required for non-porous surfaces. On porous surfaces such as concrete, stone, cement and plaster a primer (mixture of one part acrylic sealant and 4-          5 parts of water) can be applied.
• Min/max joint width must be 5mm/25mm. The recommended joint depth/width ratio is 1 to 2.
• Application temperature is between +5 °C and +35 °C.
• Immediately after the application, smooth the sealant at once with wet finger or a wet tool. Excess sealant can be removed by a wet cloth.
• Keep the sealed joint dry at least for two hours.
• Cured sealant can be removed mechanically.
