Paint & Coatings

Coatings and paints are ubiquitous in our everyday lives for decorative and aesthetic purposes, but also to protect and isolate the covered surfaces and materials from their environments. For example, metallic surfaces would oxidate very quickly without any suitable protection from corrosion. These functional layers can add new functionalities to the substrate too. From our modern smartphones’ screens covered by anti-fingerprint top-layer coatings to avoid unsightly traces on their surfaces to self-healing varnishes applied on polymeric matrices to reduce cracks: coatings are employed in diverse domains.


Paints and coatings are formulated to meet specific requirements in terms of properties. Their application on various materials is dependent from a suitable wettability on these substrates. For that purpose, our functional molecules can be used as additives or precursors to tailor the surface energy of the blend and provide good wetting of the surface to apply a homogeneous layer.

Adhesion Promotion

Moreover, to ensure their protective and functional roles, coatings need to present a good adhesion on the covered parts. For that reason, adhesion promoters can be applied preliminary on the surface. Our bi-functional molecules can play this role by creating chemical bonding at the interface: one functional group will react with the substrate and the second chemical group with the matrix of the coating to provide covalent linkage, which will ensure a long-lasting attachment of the layer on the material.

Dispersibility and Stability

Various fillers and precursors can be used for formulating the adequate coating to reach the chosen color and finish, mechanical resistance, adapted rheology, etc. A proper dispersibility and a good stability are essential to limit unwanted issues like flocculation, demixing or dephasing of the formulation, need of high shearing rates before application, or inhomogeneity of the final covering layer.

Green Coatings

The market of Green Coatings is constantly growing and projected to reach near 156 billion dollars by 2027. This trend includes waterborne, powder and high solid content coatings to limit the use of harmful solvents.
