Conagen recently announced the development of debondable hot-melt adhesives made with high-performance materials from sustainable and natural biomolecules. According to the company, it leverages its precision fermentation technology to engineer a synthetic pathway independent of plant source materials, creating more efficient and sustainable bio-based ingredients than what can be achieved with chemically synthesized versions.
Most reactive hot-melt adhesives rely on post-curing chemistry to develop adhesive strength. A downside to this approach is that the curing process is irreversible and, as such, hinders or prevents debonding almost entirely.
