Invisible Materials, Visible Impact: Lessons from tesa’s Bangkok Center

By: Neha Sarraf

I recently visited tesa’s new Bangkok Customer Solution Center, and it was one of the most insightful industry experiences I have had in a long time. I believed it to be a standard supplier tour turned into a genuine eye-opener about why high-performance adhesives are quietly powering the smartphone revolution, the electric vehicle surge, and Southeast Asia’s manufacturing rise. tesa, a German company over 125 years of history, €1.7 billion in annual sales, and over 7,000 products, is making a major strategic bet on Asia. The company aims for Asia to generate as much revenue as Europe does today by around 2026, backed by a 70,000 m² production facility in Haiphong, Vietnam, new offices in Hanoi, and this cutting-edge Customer Solution Center in Bangkok.

What makes the visit especially valuable is how it bridges theory and practice German engineering precision combined with local, on-the-ground support. I also witnessed a live demonstration of “ELSA,” tesa’s AI-powered platform that gives engineers instant access to test data, specifications, and tailored recommendations on demand.

Inside the Lab

Walking into the facility felt like stepping into a high-tech lab than an office. Climate-controlled testing chambers, advanced simulation equipment, and on-site engineering support allow real-time problem solving. I experienced live demonstrations of ultra-thin tapes securing smartphone displays, aligning camera modules with incredible precision, and protecting battery systems in demanding conditions.

The numbers don't lie

A flagship smartphone can contain up to 70 different tape applications. These are not ordinary adhesive tapes, they manage heat, vibration, weight reduction, waterproofing, and high-voltage safety, including those Bright orange wire-harness tape markings on critical high-voltage tape.

Deboning on demand

One of the most impressive moments was seeing tesa’s “Debonding on Demand” technology in action. With heat, electricity, or laser, bonds that are strong enough for the harshest conditions can be released cleanly on command making repairs and recycling far more practical. This forward-thinking approach directly supports the circular economy goals of EV and battery manufacturers worldwide.

Why these visits matter

It is one thing to read about advanced materials; it’s another to watch them tested under real conditions and speak directly with application engineers solving tomorrow’s manufacturing challenges. For students, researchers, or professionals connected to institutions like AIT, these visits turn abstract concepts into clear, career-oriented insights which cannot be replicated by reports or emails. Sometimes the most important advances come from materials nobody ever sees. tesa’s work is a perfect reminder of that truth.
