Recherche et développement

We provide research with human and technological means enabling to progress regarding chemistry, physico-chemistry, mechanics, application and curing processes.

To achieve this goal, there are several development orientations:

 

  • The design of the binder / hybrid matrix structure (organo-mineral) used in our water-based systems (Sol-Gel process) is fundamental because the optimization of the binder structure allows to design, control and ensure the reproductibility of the physico-chemical functions and performance for a coating.

  • The comprehension of « sacrificial » protection mechanisms, which requires a good stability of water-based zinc and aluminium metallic flakes in order to avoid an hydrogen emission is also a key issue.
  • The study of particles passivation systems allows to get a long-lasting protection of the coating.
  • The knowledge in physico-chemical interactions between binders, pigments, additives and surfactants is necessary to obtain a good stability of the liquid compound (aqueous phase) and optimize the performance regarding : wettability - rheology – film tension - adhesion-cohesion – lubrication
  • The characterisation and elaboration of tribology properties are also key issues when designing our coatings. The strategy and control of tightening/clamping function for the automotive industry is indeed essential in order to optimize each assembly, avoid over measurements and get the lower cost.

All these developments are carried out within our international anticorrosion group NOF METAL COATINGS GROUP. We use major means and equipments of physico-chemical analysis in our laboratories in Europe, Asia, North and South America.

Moreover, thanks to a closer cooperation with universities worldwide, we have access to additional analyse and characterization equipments, we can develop and use the latest knowledge (ex: nanotechnology…) by diverse scientific communities.
