Senior Scientist, Sika Technology
Dr. Nico Bordeanu holds an MSc in Chemistry and a PhD in Organic Macromolecular Chemistry (University of Saarbrücken, Germany). With over 17 years at Sika Technology, he has contributed to global R&D efforts in thermoplastic and thermoset foam development across Switzerland and the USA. As a Senior Scientist in Corporate Research, his work focuses on advanced adhesive technologies with a particular emphasis on debonding-on-demand concepts to enable circularity and disassembly. His expertise includes 1C- and 2C-epoxy systems, toughening strategies, epoxy and EVA-based foams, and new PUR and PO hotmelt platforms. He is also experienced in polymer synthesis, rheology, foamability, and DMTA characterization.
Debonding-on-Demand: Smart Adhesive Technologies for Circular Automotive Design
As regulatory pressure and sustainability targets intensify, the adhesives and sealants industry must develop solutions that combine high performance with circularity.
This presentation at FEICA 2025 will first highlight Sika’s latest bonding innovations across key chemistries such as epoxies, polyurethanes, silane-terminated polymers (STP), acrylates, and silicones, engineered for optimal strength, elongation, adhesion, and curing speed.
To support circular design, particularly in automotive applications where 95% recyclability is future-mandated, Sika has integrated Debonding-on-Demand (DoD) functionality into these systems via advanced primer technologies. These primers enable controlled disassembly without compromising initial bonding performance.
The presentation will highlight two industry-ready debonding primer systems, their debonding mechanism and properties.
Under evaluation by OEMs, these solutions show how structural adhesives can be made circular—opening new opportunities for sustainable design and end-of-life management.
