A 4L tub of PROMASEAL Grafitex for sealing Promaseal Conduit Collars.
PROMASEAL® Grafitex is an intumescent compound unaffected by water and moisture when cured. It is designed to expand and fill the gaps around the penetrating services when exposed to fire and any that may occur at where combustible type services melt or distort. In general PROMASEAL® Grafitex is used in lieu of a fire resistant sealant where a penetrating service insulated by combustible materials or the service itself is combustible, e.g. uPVC conduits. It is not applicable for metal services or electrical cables. For these applications, please refer to PROMASEAL®-A Acrylic Sealant, PROMASEAL® IBS™ or PROMASEAL® Mortar. PROMASEAL® Grafitex is not designed for use in gaps or joints where a high degree of thermal movement is expected.
