EMSHIELD DFR2 features a traffic-grade silicone sealing surface on both the upper and lower faces, adhered to a fire-retardant impregnated foam backing. The system is installed into epoxy adhesive field-applied onto the joint faces. A field-injected silicone sealant band seals the bellows to the substrate at the traffic surface. (NOTE: DFR2 was tested and passed UL 2079 without installation of sealant bands from the underside and these are therefore NOT needed). Joins between each stick are executed using a field-applied silicone sealant at the top and bottom of the join and field-applied intumescent sealant on the adjoining foam faces. Movement Capability – +50% and -50% (100% total) of nominal material size. Use for expansion joints in decks and floors where watertightness and/or a fire-rating and/or traffic durability are required.
