Flex 310 M FireSeal is a permanently elastic adhesive and sealant based on SMP with a fire resistance up to 120 minutes. Tested and classified for all joint structures according to EN 1366-4. The paint-compatible sealant with very low volume shrinkage meets the highest demands in terms of fire protection, such as the requirements of the International Maritime Organisation IMO FTPC Parts 2+5 as well as for rail vehicles in accordance with DIN EN 45545-2 R22/23 HL3. The very low emissions allow safe indoor application.
Flex 310 M FireSeal adheres very well even to powder-coated, painted, galvanised, anodised, chromated and hot-dip galvanised surfaces. It is suitable for use on metal, plastics, concrete and wood. The adhesive and sealant can be used in many application areas. It is suitable for fire barriers and covers, for joints in non-structural components with fire resistance requirements, for connection joints and for sealing cable ducts, pipe openings and housings. Flex 310 M FireSeal can also be used in other industrial areas, such as vehicle and body construction, container construction, apparatus and fittings construction, the energy and electrical industries, insulation technology and plastics technology.
