KOMPOSISI FLUORO KIMIA TERDIRI DARI BAHAN PENGEMBANG ISO SIANAT DIBLOK DAN METODA PENGOLAHAN DARI BAHAN DASAR BERSERAT DI SINI

摘要

The present invention provides a fluorochemical composition for treatment of a fibrous substrate. The fluorochemical composition comprises at least one fluorochemical compound and a blocked isocyanate extender derived from a condensation of a polyisocyanate, a diol selected from the group consisting of fatty ester diols, polysiloxane diols, polyester diols, polytetramethylene glycol, dimer diols and mixtures thereof and an isocyanate blocking agent. The present invention also provides a fibrous substrate treated with the above composition and the use of the above fluorochemical composition to impart water and/or oil repellency to a fibrous substrate.
