JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
The company is launching the first line of hybrid structural adhesives, called INES for INterlaced Elastomer NetworkS. The new adhesives offer high structural and damping performance.
The INES line combines the performance of three different adhesive bonding technologies: the resistance and mechanical strength that only epoxies can usually offer; the elasticity provided by polyurethanes (PUR); and the fast assembly rate enabled by methacrylates (MMA). This is the first time that a structural adhesive combines elongation, low modulus and high mechanical performance with high impact, peel and shear strength, for a range of temperatures from -80° to +140°C.Peerless compatibility between heterogeneous materialsThere is no need for a primer with INES to obtain high performance: the bond remains flexible, yet allows rapid handling of the bonded parts. Furthermore, this adhesive can be used to join the broadest range of heterogeneous materials found in the market: treated metals, engineering composites (include carbon fibre, CFRP, SMC, BMC and RTM), thermoplastics (ABS and PC), glass, zinc, etc. “Our durable high-performance multi-material adhesives target many different applications, and can create reliable adhesive bonds where welding and riveting are now used, in particular to assemble composite materials and metals. Our adhesives are already used by world-renowned companies for large parts in sectors as demanding as automotive (chassis, bodywork), boating, railway, and even aerospace!”, said Aderis Innovation Director Arnaud Curet.A combination of exceptional propertiesThis new product has excellent elasticity (70% pure elasticity over an elongation range) in combination with high strength (250 kg/cm² for shear on steel and up to 100 kg/3.5 cm for peel). These properties offer exceptional technical performance for high-stress bonding applications: thanks to its high structural performance, it acts like a damper jack when the assembly is subjected to vibrations, over a range of temperatures from -80° to +140°C (the product’s two glass transition temperatures). The damping feature is also acoustic as it mitigates noise, especially when it is used on automotive parts. In addition, unlike the adhesives on the market today, the INES range performs at ambient temperature, which means considerable time and energy savings for users.More information:www.aderis-specialties.com
