Description

Fire Retardant Silicone Sealant is a single-component, gun-grade, ready-to-use neutral silicone sealant formulated to form an elastomeric fire retardant seal in construction applications. It helps control the spread of fire, smoke, and toxic fumes within a given area surrounded by firewalls for a period of up to four hours, depending on the joint configuration.

 

  • Fire rating up to 4 hours (BS EN 1366-4: 2006)
  • ASTM C920 compliant
  • ±50% movement capability
  • Excellent weather and UV resistance
  • Excellent adhesion to most substrates
  • Matte finish

 

 

Recommended for firestop sealing of interior and exterior building and construction joints, where a fire rating of up to 4 hours is required. It may be used to seal vertical and horizontal joints between metals, masonry, concrete and other common construction materials.

Joint Design

  • The specified sealant bead size should be calculated to comply with the compression and extension capabilities of the sealant in relation to the anticipated joint width due to expansion and contraction.
  • Generally, calculation of the width sealant bead should be computed on the basis of a maximum ±50 % movement capability
  • Minimum joint depth should not be less than 6 mm to accommodate movement.
  • Sealant design joint width-to-depth ratio should be 2:1.
