Comparison between one step and multistep fire retardant coating processes by Life Cycle Assessment

Abstract : The setup of a functional coating on a substrate usually requires different layers, each of them having a specific role: a primer or a surface treatment to enhance the adhesion of the coating onto the substrate, an intermediate functional layer (e.g. with flame retardant properties) and a protective topcoat to avoid or limit the ageing. However, these multi-layered systems require the use of at least two different formulations as well as complex application and curing procedures which are not always in accordance with industrial and environmental constraints. Moreover, adhesion between layers is often an issue. The self-stratifying approach represents an innovative way to reduce the number of layers, while maintaining or upgrading the overall performance of current coatings. A self-layering system is based on incompatible polymer blend which spontaneously stratifies after its application on a substrate. This approach allows avoiding the interfacial adhesion failure between layers that can be found in multi-layered systems. Recently, efficient flame retardant and weathering resistant self-stratifying coatings were designed in our team, and the present study aims at comparing, using Life Cycle Assessment (LCA), the environmental impact of these self-stratified systems compared to a classical two-layered coating.
