Intumescent Sealant is a high specification one part water based acrylic sealant. Easily applied using a standard cartridge sealant gun.
Intumescent Sealant is suitable for sealing joints and service penetrations in fire walls, partitions, fire rated door frames and glazing systems. Intumescent Sealant provides up to 4 hours fire protection in joints of up to 30mm wide. In addition to the fire rating, the sealant may be used to seal joints in party walls to provide an acoustic seal.
The depth of the joint will depend on the gap to be filled and the fire rating required. All surfaces must be thoroughly clean and free of bond breaking contaminants prior to application of the sealant. No priming is required for most construction substrates; however, it is recommended that a small area be tested on substrates.
The sealant should not be applied if the ambient temperature is below 5ºC as adhesion will be impaired. The sealant is fast curing approximately 15 minute tack free time. When fully cured, the sealant is over paintable. Under fire conditions the sealant forms a fire resistant ash.
