Firecote Intumescent Sealant

 
 

A flexible intumescent sealant supplied in standard cartridge form for the prevention of fire and gas penetration through small service penetrations and internal joints and cracks for up to 4 hours.

 

Description

Firecote Intumescent Sealant is a one part emulsion acrylic based sealant. It gives a firm yet flexible seal to joints in virtually any fire rated structure. Under a high temperature load it will char and swell up to three time its orginal size resisting the passage of fire for up to four hours.

 

Application

Firecote Intumescent Sealant is appropriate for sealing joints, voids and irregular holes in fire walls, partitions and other structures, and for maintaining their integrity when sealing around pipes and cables that penetrate them. It can also be used for internal perimeter pointing of fire rated door and window frames.

Sitework

The sealant must not be applied below an ambient temperature of 5 degrees C.

Ensure all surfaces are clean and dust free. Priming is not normally required but unusual substrata shoud be tested. Insert polyethylene foam backing into the joint to a depth of 1Omm below surface. Gun apply the Firecote Sealant to a smooth, flush finish.

Joint width must be at least 6mm and can be up to 25mm. A 10mm deep single seal will give a fire rating of 2 hours. A dual seal i.e. a single seal on each side of a wall or floor will give 4 hours fire rating.

Single seals should be on the fire rated side of the structure.

Where a neat finish is required use masking tape which should be removed immediately the sealant is smoothed off.

 

Authority

Firecote Intumescent Sealant is manufactured under ISO 9001 "Quality Systems". Fire integrity for up to 4 hours has been fully tested to BS 476: parts 20 and 22: 1987 "Methods of determination of the fire resistance of non loadbearing elements of construction".
