Researchers at Purdue University in the US have discovered that tannic acid, currently used in widely divergent fields such as medical treatment, leather tanning, ink manufacture and as a flavoring for certain drinks, could prove equally beneficial in the adhesives, coatings and manufacturing composites sectors. The researchers report that their technological research has shown that this acid could also add some extra benefits like lower cost and sustainability in the process.

Its new role would be as the hardening agent added to the polymer to ensure its stability and rigidity in environments with high temperatures. According to the research team, using tannic acid as a hardener would also reduce the cost and improve durability, while at the same time lessening the environmental impact of the adhesives, coatings, structural composites, insulating materials and electronic components for which epoxy polymer is used.
