Bio-based adhesives have been a hot topic of conversation in recent years due to their environmental advantages over traditional chemical adhesives. But now, researchers have developed a bio-based adhesive that is not only eco-friendly, but also stronger than traditional chemical adhesives.

In a recent study, researchers from the Institute of Technology of Catalonia (ITC) have developed a bio-based adhesive derived from two natural polymers, chitosan and poly(vinyl alcohol) (PVA). This new adhesive was found to have a greater tensile strength than chemical adhesives. The researchers tested the adhesive on a variety of materials, including wood, metal and plastic, and found that it was able to form strong bonds on all of them.

The researchers believe this new adhesive could be a great alternative to traditional chemical adhesives, as it is not only more eco-friendly but also stronger. This could open up a range of new possibilities for green product manufacturing and construction.
