Definitions

  • the present invention relates to aminosiloxane or aminopolysiloxane-containing waterproofing agents for leather.
  • a particular advantage of this barrel waterproofing on wet leather compared to waterproofing with silicones or fluorocarbons, which are applied to dry leather in a post-treatment mostly from water-immiscible organic solutions, is that they are used completely or at least partially in place of the customary licker lubrication can and in addition to the actual hydrophobization softens the leather (see e.g. preparations made from natural and / or synthetic fatty substances and waxes as well as paraffin hydrocarbons with emulsifiers, which are fixed by fixation with acids or metal salts and thereby lose their hydrophilicity).
