Application

The sealant is supplied in liquid form and can be either gunned or trowelled into the aperture, in or between the separating elements to a specific depth, utilizing various backing materials (mineral wool; minimum of 80 kg/m³, or PE backing rod). For use in low movement joints, and tested in the following locations:

  • Walls of 100–250 mm thickness.
  • Rigid floors of 150 mm minimum thickness.
  • Linear joints up to 50 mm wide.
  • Large service openings up to 490 x 150 mm.
  • Metallic pipes, cables, cable bunches, cable trays and cable ladders.

Description

Water based, acrylic sealant used to reinstate the fire resistance of wall and floor constructions (where apertures are penetrated by multiple services), and linear gap seals (where wall and floor constructions abut).

Features and benefits:

  • Mechanical adhesion, tensile testing and shore hardness to ISO 9046:2005, ISO 8339:2005 and ISO 7619-1:2011.
  • Fire resistance has been tested in flexible walls, rigid walls and floors.
  • Causes no known effects to plastic pipes, plastic cables, sheathing or metallic components.
  • Remains flexible.
  • Halogen free, and resistant to fungi and vermin.
  • CE marked.
  • BREEAM and SPEARS approved.
