Aqueous dispersions for treating absorbent materials for protection against soiling

摘要: The invention concerns aqueous dispersions containing the following components: (A) low-molecular organosilicon compounds selected from: (A1) C1 to C20 hydrocarbon C1-C6 alkoxysilanes; and (A2) organosiloxanes C6 alkoxy groups optionally hydroxyl groups, in comprising basic nitrogen or halogen atoms; (B) film-forming organic polymers; (C) which reduce colour adhesion and/or improve permeability water vapour of coating, said being from high-molecular organopolysiloxanes fluoro-organic compounds.
