RIW MultiJoint is a closed cell, cross linked Ethylene Vinyl Acetate (EVA) copolymer foam. The manufacturing process gives a nitrogen blown, impermeable, closed cell foam. The product is waterproof and resistant to salts and most chemical attack. It also has good UV resistance and is therefore suitable for use in exposed exterior applications.RIW MultiJoint has been designed for use in all types of construction gaps and movement joints to provide a waterproofing system between the structural elements. Movement capability of up to 90% of the construction gap is achieved, and the material is chemically bonded to each structure, maintaining the waterproofing of the joint. The product has grooves along the bond surface that run the entire length of the joint, and these grooves increase the surface area and enhance the adhesion to the substrate. RIW MultiJoint Adhesive is a two part, solvent free, modified epoxy adhesive.Typical Uses:RIW MultiJoint is used to seal joints in podium decks, car parks, foot or road bridges, stadiums and sports arenas, shopping malls, airports, roofs and building façades. May be recessed into the joint, with a sealant over.Advantages:No special jointing pieces required.Easily cut and welded on site.Available in a wide range of sizes.Resists up to 20 m head of water.RIW MultiJoint:- Material: Closed cell foam.- Compression stress-strain to BS ISO 7214:1998:10% = 30 kPa.25% = 51 kPa.40% = 82 kPa.50% = 115 kPa.- Tensile strength to BS ISO 7214:1998:840 kPa.- Tensile elongation to BS ISO 7214:1998:245%.- Tear strength to BS EN 8067:1995:1055 N/m. - Recommended operating temperature range:-70°C to +65°C.- Thermal conductivity to ISO 8302:1991 (mean temperature of 10°C):0.0404 W/mK.RIW MultiJoint adhesive:Pot life: 45 minutes at 15°C.Tack time: 90 minutes.Full cure: Eight hours minimum.
