Our epoxy hardeners offer excellent corrosion protection and are available in both aqueous and solvent-free versions. Based on this, our bio-based polyols develop outstanding properties for coatings that meet the high demands for aesthetics and durability in rail vehicle production. Our products are characterised by high resistance, even to the most aggressive cleaning agents. They are also suitable for applications in foams, adhesives and sealants. There they reduce the share of fossil raw materials in the formulation: Merginol 903 has a bio-based carbon content of 88 %.
