Fire Protect Acrylic Sealant has been formulated to be fire resistant up to 4 hours. This is particularly important for the construction and cladding industries. CTA Fire Protect will not support combustion. Its special intumescent properties cause the sealant to swell up and char in the presence of heat, preventing the spread of smoke and fire through the joint. The curing method is water based. Therefore, no solvent or halogens present. White in colour and available in standard 310ml cartridge.

Fire Protect applications
CTA Fire Protect is ideal for many construction and cladding applications. Such as: voids and irregular holes in fire walls, fire rated ducting; joints, partitions, door architraves, floors and other structures. Bedding of hinges and locks in fire doors. Perimeter sealing of internal, fire rated screens, partitions, service penetrations and door or window frames.
Materials that can be bonded with Fire Protect
CTA Fire Protect also provides good adhesion to timber, plasterboard, masonry, blockwork, plaster and concrete. To maintain integrity when sealing around pipes, services and cables.
Application temperature range: +5°C to +30°C.
Curing rate: No curing reaction takes place. Dries through evaporation.
Shelf life: 12 months (DO NOT STORE BELOW 5°C).
Skinning time: skin forms within 25 minutes at 20°C @ 65% RH. (working time is 5 mins)
CTA Fire Protect acrylic sealant is a waterborne one-part fire-resistant and acoustic rated joint sealant which provides a firm, yet flexible seal to joints in a wide variety of fire-rated structures where fire resistance up to 4 hours is required. Its special intumescent properties cause the sealant to swell up and char in the presence of heat, preventing the spread of smoke and fire through the joint.

Surface preparation and Instructions
All surfaces must be clean, dry and free from frost, grease and loose materials. In situations where an especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed. Cut the tip of the screw thread off the cartridge and screw onto the nozzle. Cut nozzle to the correct diameter for the joint size, apply using a skeleton gun. Gun sealant into joints ensuring there are no voids or gaps and that the sealant is in full contact with both joint surfaces.
