There is an increasing demand for green products, but for them to be genuinely sustainable, manufacturers must also use adhesives and paints that are made of bio-based feedstocks. Advanced materials developed in Fraunhofer labs point the way forward. Demand for organic products is booming. Factory farms and fields drenched in chemi-cal cocktails hold little appeal for the many consumers who prefer to see free-ranging animals in verdant pastures, eat untreated fruit and vegetables and wear clothes made of organically grown, pesticide-free cotton. It is not enough, however, merely to re-place plastic with natural materials such as wood or cork. For products to be genuinely sustainable, manufacturers must also use adhesives and paints that are made of bio-based raw materials. Most legacy adhesives are made of petroleum-based thermosetting epoxy resins. These are synthetic resins that hold their shape once they have been heated.
