What if araminolic resins were compatible with your applications?
Araminolic resins are polymers synthesized from polyphenols and aromatic aldehydes.
Polyphenols are often naturally occurring molecules and are well known for their antioxidant properties. Among these, flavonoids or tannins, which can be found in fruit or wood, constitute monomer bases that are mostly non-toxic and derived from renewable resources.
Certain aromatic aldehydes also exist in their natural state, such as 5HMF, which is derived from the dehydration of fructose, found in fruits.
The chemistry of araminolic resins relies on the reactivity of these polyphenols and aromatic aldehydes to form distinctive and non-toxic polymers. Araminolic polymers are described in greater detail in document WO2017/168107.

Araminolic resins can be used in a wide range of applications as an adhesive or matrix. Like phenolic resins, araminolic resins can provide high temperature resistance to the materials with which they are associated, as well as resistance to water.
They are compatible with the historical aqueous phenolic resins and aminoplastic resins such as phenol-formaldehyde PF, urea-formaldehyde UF resins and melamine-urea-formaldehyde MUF resins. In particular, our resins make it possible to replace all or part of the toxic molecules found in phenolic resins, such as phenol, formaldehyde, resorcinol and melamine.
They can therefore increase the biobased content of these resins, which are usually derived from petrochemicals.
Araminolic resins can be used as additives in other chemistries to optimize the technical and industrial performance of formulations. Our resins are compatible with resins derived from biomass, such as lignin-based resins from hardwood or softwoods lignosulfonate and organosolve resins.
Our resins naturally include aldehyde and alcohol functions. They are compatible with monomers and polymers incorporating acrylamide functions. For example, our resins can impart temperature resistance or even rigidity. The same is true when combined with epoxies or acrylates in aqueous solution.
More generally, araminolic resins are compatible with polymers with alcohol functions, such as soluble polyesters or polyols.
