Résumé : |
Solvent-borne epoxy coatings dominate the marine, petrochemical and infrastructure protective coatings markets. However, current lower VOC epoxy formulations may have high viscosity, poor spray application and reduced corrosion resistance. A novel low viscosity epoxy can provide ultra-high solids coatings with improved sprayability and excellent corrosion resistance. The global marine and protective formulated coating market in 2010 was valued at US$ 12 billion [1]. This market is dominated by the use of epoxy resin systems with a 60 % market share due to the inherent need for corrosion resistance and durability. Polyurethanes, in second place, hold only a 14 % market share.
However, there is still a need for new materials to address the limitations of epoxies. For example, standard epoxy resins are very viscous (or solid) and therefore require a significant amount of organic solvent to achieve sprayable paint viscosities and facilitate application onto substrates. |
