Aderis, an adhesive supplier based in France, has launched its first line of hybrid structural adhesives, called INES for INterlaced Elastomer NetworkS.
According to the company, 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).
Aderis says 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°C to 140°C.
There is no need for a primer, the company notes, as the bond remains flexible, yet allows rapid handling of the bonded parts. Furthermore, INES can be used to join a wide range of heterogeneous materials: treated metals, engineering composites, 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.
INES has 70% pure elasticity over an elongation range with high strength, at up to 250kg/cm² for shear on steel and up to 100kg/3.5cm for peel. It acts like a damper jack when the assembly is subjected to vibrations, over a range of temperatures from -80°C to 140°C, the product’s two glass transition temperatures. Moreover, INES mitigates noise, especially when it is used on automotive parts.
The company adds that INES range performs at ambient temperature, which saves considerable time and energy.According to Mr Curet, the company will be using bio-sourced, recyclable materials to the extent of 50% within five years.
