Aderis Launches New Hybrid Structural Adhesives

11 June 2013

Aderisis launching INterlaced Elastomer NetworkS (INES), its first line of hybrid structural adhesives.

Aderis says the new adhesives offer highstructural and damping performance, combining 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).

They say this is the first time that a structural adhesive has combined elongation, low modulus and high mechanical performance with high impact, peel and shear strength, for a range of temperatures from -80° to +140°C. The bond remains flexible without using a primer and allows rapid handling of bonded parts. Furthermore, INES can be used to join the broadest range of materials found in the market, such as treated metals, engineering composites, thermoplastics (ABS and PC), glass, and zinc.

“Our durable, high-performance, multi-material adhesives targets 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, boating, railway, and even aerospace!” said Aderis Innovation Director, Arnaud Curet.

INES has an 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, the INES line 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 INES mitigates noise, especially when it is used on automotive parts. “INES is a truly ground-breaking technology that enables manufacturers to make assemblies safer over the long term and for which the extremely high level of performance and reliability inspires greater confidence in the bonding process”, pointed out Mr Curet.

In addition, the INES range performs at ambient temperature, which means considerable time and energy savings for users.

According to Mr Curet, the company will be using bio-sourced, recyclable materials to the extent of 50% within five years. “Aderis is at a turning point of its development, and we hope to position ourselves in sustainable mobility markets, thanks not only to the innovative performance offered by our products, but also to the minimised carbon footprint they can provide to our customers”.
