Composition for rendering a paper or textile base resistant to water, oil and solvents, treated base and process for the production of the treated base

Abstract

Coating and impregnation of bases. The invention relates to a composition for impregnating a base, more particularly a paper or textile base, said composition being intended to provide said base with barriers, especially at least hydrophobic barriers, and including glyoxal, the composition also being intended to provide oleophobic and solvanophobic properties simultaneously and comprising the following, by weight of dry product relative to the base: at least 0.03% of glyoxal, at least 0.01% of a dimeric alkylketen and at least 0.002% of a fluorinated salt selected from the family of the diethanolamine salts of perfluoroalkyl ethyl phosphates. Composition for rendering a paper or textile base hydrophobic, oleophobic and solvanophobic.
