Bio-based raw materials for paints and varnishes follow the megatrend towards more sustainability. The additives are, of course, the smaller part of a coating formulation, so the pressure to switch to biobased is not as high, but the trend has nevertheless arrived in this area as well. In the case of binders, there is partly a return to old materials such as natural oils and resins. In addition and increasingly, there are also polymer building blocks that are obtained from renewable raw materials. Bioalcohol is a byproduct of waste material, other building blocks are also produced via fermentation. These basic ...
