Fire Rated MS Sealant
ALSEAL Fire Rated MS Sealant is a single-component, moisture-curing sealant based on advanced MS
Polymer technology that provides movement capability in fire rated joint applications. It is compliant with fire
rating specification of BS EN 1366-4:2006. It can be painted over with common industrial paints; sealant bead
will not shrink after cured; and the isocyanate-free formulation makes it possible to work on damp surfaces and
will not have air bubbling issue. Even without primer, adhesion on various substrates is excellent. It is a green
sealant formulated to meet the low VOC regulation.
Recommended for sealing all building and construction joints and is used to provide fire protection to gap and
movement joints. It is used for sealing interior and exterior movement joint where a fire rating of up to 4 hours is
required in precast and in-situ concrete, expansion and construction joint, tilt-up construction, brick and
blockwork, fibre cement board, plasterboard etc. It is also used as joint sealant and gap filler against dust and
water penetration, and sealing joints, voids and irregular holes in fire walls, partitions and other structure.
