Global Expert Unite

Advancing the Future of Industrial Adhesives at Symposium In Adhesives 2026.

On March 3–4, 2026, experts from across the automotive, composites, electronics, and industrial sectors convened in Munich for the annual In-adhesives Symposium, one of the most influential scientific events dedicated to adhesive technologies.

L&L Products R&D materials specialist, Michel AWKAL, presented the challenges of creating structural adhesives for lightweight composite motor vehicles, why traditional welding fails and give way to polymers, how a unique blend of phase-separating tougheners and high-molecular-weight polymers unlocked breakthrough fatigue resistance, the surprising science behind localized yielding, and much more.

A Global Gathering for Adhesive Innovation

The 2026 edition of In Adhesives brought together more than X researchers, OEM specialists, and materials scientists from around the world for two days. Participants engaged with a scientific program that spanned renewable polymer chemistry, plasma-enabled surface engineering, AI-driven R&D, next-generation polyurethane systems, and advanced lamination technologies — reflecting the rapid evolution of adhesive science.

Hands-on innovation stations and technical exchanges complemented the formal agenda, giving attendees the opportunity to explore emerging solutions in composite bonding, lightweight structural design, process automation, and data-driven formulation optimization. These interactions underscored the growing convergence of chemistry, engineering, and digital technologies in shaping the future of adhesives.

Across automotive, aerospace, construction, electronics, optics, and medical applications, the symposium fostered forward-looking discussions on how advanced bonding technologies will enable more efficient manufacturing, more durable structures, and more sustainable material systems in the years ahead.

The L&L Touch: Advancing Structural Bonding for Composite Vehicle Architectures

During the symposium, Michel Awkal, Research & Development Engineer at L&L Products, presented groundbreaking work on a fatigue- and impact-resistant structural adhesive designed specifically for lightweight composite motor vehicles.

His presentation addressed a central challenge in modern vehicle engineering: as manufacturers transition from welded metal structures to polymer composite architectures, traditional joining methods are no longer viable. Adhesive bonding becomes essential — but only if the adhesive can withstand both extensive cyclic loading and single-event high-stress impacts, a combination that has historically been difficult to achieve.
