...ient, because solvents do not need to be distilled, and the product does not have to pass the drying tunnel. Drying Demands Half the Energy Bayer MaterialScience has developed aqueous “High Solid” PUDs with a high solid content (60 %, grade: Impranil) for transfer coating. Using these materials, sufficiently thick layers of foam can be applied in one single processing step, in most cases, thus stepping up performance and production speed. But most of all, less water steam is necessary, and this ...
