Are you looking for:

⇒ Up-to-date information about sol-gels?

⇒ Up-to-date information about functional coatings?

Substitution of a CMR product in your process?

⇒ Advice in the choice of materials for your application?

⇒ Relevant regulatory limitations concerning coatings and nanomaterials?

⇒ Help to draft your specifications?


Our experts are ready to help you in your innovation process and give you all the relevant information:

-on mono- and multifunctional sol-gel coatings

-on functionalities such as hydrophobicity and superhydrophobicity, conductivity, dry lubrication, protection against corrosion, biocide, their use and limits

-on sol-gel metal oxides and their use (catalysis, OPV, batteries)

-on the different types of conductive ink

-on funding (French or European projects)

-on regulatory issues connected with functional coatings


All our activities are eligible to the Research Tax Credit (CIR) and we hold the certificate of approval issued by the Ministry of Research.
