Aderis introduces new range of hybrid structural adhesives

[image_0]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 (PU); and the fast assembly rate enabled by methacrylates (MMA). According to Aderis, 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 (the product's two glass transition temperatures).There is no need for a primer with Ines, says the company. The bond remains flexible, yet allows rapid handling of the bonded parts. Furthermore, Ines can be used to join the broadest range of heterogeneous materials found in the market: treated metals, engineering composites (including carbon fibres, 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 properties [image_1_right]According to the company, Ines has a high 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. The damping feature is also acoustic: 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”, said Curet. 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. According to 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 minimized carbon footprint they can provide to our customers”, he said. With more than 30 years of experience in adhesives and sealing technology, and facilities located near Paris, France, Aderis develops and produces structural adhesives for the aerospace, electronics, automotive, railway and transportation, building and construction, as well as sports and leisure sectors. The company has already filed five international patents and expects that exports will account for nearly half of its sales by 2014.
