Description

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.

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.
