New very high solid acrylic polyol binders for low VOC direct-to-metal two components system

Metals are excellent materials with high strength and mechanical properties. However, when they are exposed to corrosive environment, surface will corrode, creating a potential danger and reducing its service life. Today, the corrosion protection is often obtained by multi-layer systems involving at least a primer and a top coat. These two coats could be based on different technologies including solvent borne and waterborne binders. In order to reduce the level of volatile organic compounds, Arkema has developed a new very high solid solvent borne acrylic technology that provides a high protection to corrosion. This new binder offers the advantage that it can be used as single Direct To Metal coating and allows to have a paint formulation below 250g/l of VOC. The new properties will be presented, as well as mechanisms and fundamentals which have been used to develop the technology.
