Product Description:


PROMASEAL® Intumescent Sealant is a white or grey waterbased acrylic intumescent sealant supplied in a 310ml cartridge. PROMASEAL® Silicone Sealant is a silicone-based fire protection sealant, available in white, grey or black, supplied in 310ml cartridges. Adhesion is excellent to most types of surface.  The sealants cure in air to form a nonhardening, tack-free seal, preventing the passage of smoke, toxic gases and fire.


Both PROMASEAL® Intumescent Sealant and PROMASEAL® Silicone Sealant are suitable for sealing small gaps and holes in applications requiring up to 240 minutes fire resistance. PROMASEAL® Intumescent Sealant is suitable for most applications but the PROMASEAL® Silicone Sealant would be required for service temperatures over 70oC or where increased joint movement capability is needed.


The fire performance of PROMASEAL® Sealants will vary according to the particular application, the surrounding substrates, the depth of sealant applied and the amount of sealant exposed to heat.

PROMASEAL® Sealants have been tested to the procedures and adopting the criteria of BS 476: Part 20: 1987. Please note that if the fire risk is from both sides of the gap, then the systems described above should be installed on both sides.  For situations not covered by the above, please consult the Promat Technical Services Department.
