FAQs - Frequently Asked Questions

What are natural polyphenols?

Polyphenols are organic compounds found mainly in plants and fruits, which have the function of protecting them against insects, ultraviolet radiation and microbial infections.

Tannins are polyphenols of plant origin, with molecular weights generally between 500 and 3000 atomic mass units. They are classified as hydrolysable or condensable, according to their carbon skeleton.

Hydrolysable tannins are made up of several molecules of phenolic acids, such as gallic and ellagic. They are called hydrolyzable, since their ester bonds are susceptible to hydrolysis by acids or enzymes.

Condensed tannins are made up of flavonoid units, with different degrees of condensation. They are compounds that are more resistant to fragmentation.

The tannins present in Black Acacia are of the condensed type.

Adhesives can be of natural origin or synthetically produced. The first use of adhesive substances occurred about 200,000 years ago. The first references to adhesives in the literature appeared around 2000 BC.

The chemical composition of tannins allows its application in several products to replace some component of non-renewable origin. In adhesives, tannins act by reducing formaldehyde emission, the main environmental problem associated with wood panel adhesives derived from fossil resources.
