Abstract (en)
[origin: WO2021080491A1] The present invention relates to lignin-containing compositions comprising: 10 to 50 percent by weight of lignin; 10 to 50 percent by weight of a polyethylene glycol; 10 to 50 percent by weight of an acrylic resin; and 1 to 50 percent by weight of an inorganic filler; wherein the percentages by weight are expressed relative to the total dry weight of the composition, and wherein the total dry weight of the composition amounts to 100 percent. The present invention further relates to processes for sealing joints or coating surfaces using such a composition. Moreover, the present invention relates to joints sealed and surfaces coated using such a composition, as well as vehicles comprising such sealed joints and coated surfaces.
