Today, the market share of biosourced raw materials is growing in numerous industries (cosmetics, detergents,) but little in the case of paints.

The aim of the NEWCOAT project, initiated by the company ECOAT, is to contribute to increasing the use of biosourced products in paint formulations.

The objectives of NEWCOAT are therefore to obtain:

  • A biosourced polymer containing more than 85% of raw materials from the oilseeds or wood sectors, without competing with food production. At present, the manufacturers have developed innovative production methods but they do not guarantee the actual presence of more than 45% biosourced raw materials,
  • The emulsification of this polymer using biosourced surface-active agents,
  • A formulation enabling the production of an Ecolabel Class A+ paint with a VOC content <1gr/litre.

The NEWCOAT project will be based on skills developed by the Research Unit on Biopolymers – Interactions and Assemblies (BIA) at the Pays de la Loire INRA Centre regarding the stabilisation of Pickering emulsions, as well as those of the INRA-INP-ENSIACET Joint Research Unit for Agro-Industrial Chemistry (UMR-LCA) with respect to innovative resins, the Institut Charles Gerhardt Montpellier (ICGM) for chemical transformations, and those of ECOAT regarding the formulation of biosourced polymers for paint. 

This work should enable improved control of the physicochemical properties of emulsions and lead to new biosourced formulations for paints.

Partners: NEWCOAT is a three-year project and will be carried out in the context of an ADEME programme (demonstrator relative to ecological and energy transition). The Nanostructure Assemblies team in the BIA Unit will work on this project in close collaboration with ECOAT, a start-up based in Grasse and a leader in biosourced polymers, as well as private sector and academic partners (UMR-LCA in Toulouse and ICGM in Montpellier).
