Abstract:
With the increased focus on sustainability the demand for bio-based materials is strongly increasing. Over the previous years a range of bio-based building blocks based on dimer fatty acid technology has been developed for the use in high performance coatings such as polyurethane dispersions, flexibilised epoxy coatings and UV-curable coatings. These building blocks bring excellent hydrolytic stability, outdoor stability, flexibility and adhesion to a wide range of substrates including plastic, metal and wood.
Recently an additional range of low viscous, amine-functional products have been developed to expand the application possibilities for bio-based materials. For epoxy resins, the technology provides similar benefits to dimer fatty acid based polyamide curatives, such as flexibility and impact resistance. However, this new curative allows for high solids formulations with good water repellency, pigment wetting and excellent durability.
For polyurea, the technology brings improved moisture and chemical resistance together with an excellent surface finish and impact resistance. Furthermore, the novel amine functional materials are fully bio-based (100% renewable carbon) and are completely non-volatile, so bring clear environmental and health benefits to the end-users.
