Henkel is expanding its Loctite MAX polyurethane (PU) matrix resins portfolio by epoxy-based high-performance materials. The target of this resin portfolio is the market of demanding automotive composite high-temperature applications like wheels. The Loctite MAX5 NextGen outstands with rich carbon look clarity while the upcoming Loctite MAX6 is a unique combination of ultra-high heat resistance and toughness.

In the upcoming event JEC World 2019, Paris- scheduled for March 12 to 14, Henkel will throw light on its latest developments of Loctite MAX PU and epoxy matrix resins technology. This has been done to address the need for lightweighting, cost-effective and as higher-performing composite solutions for the automotive industry. This trend clearly visible in the segment of wheels while the new Loctite MAX5 NextGen and MAX6 resin systems are seen as a potential contributor to weight-savings, enhanced productivity and customization of parts showing superior thermal, mechanical and visual properties.

Recently, the Loctite MAX5 backed up thyssenkrupp Carbon Components to introduce a new generation of ultra-light braided carbon motorcycle wheels. Its matrix resin offers short mold filling times and fast curing. Every set of the composite wheels can potentially save around 1.8 kg of rotating mass in comparison to conventional forged aluminum designs. Its added advantages are bike handling and fuel efficiency. The wheels have been developed in close association with Henkel in order to optimize the manufacturing process and fulfil the extremely tight tolerances as specified by the manufacturer.

Konrad Brimo Hayek, Senior Business Development Manager Chassis & Electronic Systems at Henkel says: “Following the success of our Loctite MAX2 resin for leaf springs and MAX5 resin for wheels, we have been focusing our efforts in this technology on several key challenges especially in the market of high-performance composite and hybrid wheels.”

He further went on to say: “Apart from helping OEMs and Tier 1 suppliers reduce weight on modern vehicles and two-wheelers, we had identified a growing need for composite wheel materials that would also provide higher heat resistance and toughness while satisfying demands of greater production volumes and customized surface aspect.”

Henkel’s Loctite MAX matrix resin technology has an extra benefit for the component manufacturers. It has a flexible, time and energy saving processing window which is not a feature of other PU and epoxy resins. For component manufacturers, Henkel’s Loctite MAX matrix resin technology shows a particularly flexible, time and energy saving processing window when compared with other PU and epoxy resins.

Brimo Hayek explains: “One of the challenges to meet in these tests was to balance the pressures and curing temperatures at a level low enough to maintain the stability of the foam.” He also added: “Our Loctite MAX2 matrix resin proved to offer the best solution, with an enormous potential for further minimizing the cycle time.”

These advanced matrix resins are part of the company’s strategic approach which is to build and strengthen it’s material, process and engineering expertise for large-series structural components across the entire manufacturing chain.
