Details

A high performance, flexible acrylic building sealant and adhesive which, in the event of fire,

will swell to provide a smoke resistant barrier. Up to 4 hour fire rating achievable

 

 

Uses

FIRESHIELD AC is specially manufactured to form an acoustic and fire rated intumescent barrier in construction applications. When subjected to heat Bond It FIRESHIELD AC swells (intumesces) to provide an inert barrier to smoke and flame. The fire resistance achievable with Bond It FIRESHIELD AC depends upon the joint design, depth of sealant and substrates being sealed. See detail overleaf. It is non-slumping and rapid skinning. It can also be overpainted within 1 hour with fire resistant paint.

 

Application

All surfaces to be sealed must be clean, dry and free from grease, laitence or dust that may hinder adhesion. Apply Bond It FIRESHIELD AC over a polyethylene backing rod to a minimum depth of 12.5mm. When applying the sealant, ensure all crevices are filled and there is complete contact between sealant and substrate. Tool down using a wetted spatula. Any excess may be removed using soapy water before FIRESHIELD AC dries. Do not apply in damp conditions.
