Bio-based binders Whitepaper
High-quality industrial coating systems are usually based on polyacrylates or polyester polyols containing hydroxyl groups, which can be reacted with corresponding coating isocyanates.
Sustainability is changing the requirements for such coating systems. Whereas in the past the properties of the coating systems and the price played a very important role, today sustainability is also a factor. For example, products should have the smallest possible carbon footprint, be based on bio-based or recycled raw materials, not compete with food production if possible, and not consume additional land. Meanwhile, there are many ways to make products more sustainable. Here, polyester polyols and especially their fatty acid-modified types - the alkyd resins - can offer a wide range of possibilities.
WorléePur Si Whitepaper
Urethane has been the basis for high-quality two-component coatings for decades. The development of this technology changed the coatings industry permanently, and even today a wide variety of developments are taking place on this basis. The increasing reduction of solvent contents also requires an adaptation of the base binders used. These must have a higher solids content at the same viscosity level, which requires a reduction of the average molecular weight. Suitable catalysts still ensure acceptable drying times and good reactivity here, but significantly reduce the pot life or processing time.
Our moisture-curing polyurethane-urea binders make it possible to decouple drying and processing time. However, the technology also enables the optimisation of other properties of classic polyurethanes.
