摘要:
It is possible to obtain a porous substrate having a water/oil repellent-treated surface and a moisture-permeable waterproofing film, which has favorable water/oil repellency and wash durability, through which penetration of a coating liquid for formation of the moisture-permeable waterproofing film is suppressed, and from which peeling of the moisture-permeable waterproofing film is suppressed. A water/oil repellent composition comprising a copolymer (A) having from 60 to 95 mass% of units based on a monomer having a R F group having at most 6 carbon atoms and from 5 to 40 mass% of units based on vinylidene chloride, a copolymer (B) having from 50 to 95 mass% of units based on a halogenated olefin and from 5 to 50 mass% of units based on a monomer having a crosslinkable functional group, and a medium (C), wherein the proportion of the copolymer (A) is from 70 to 90 mass%, and the proportion of the copolymer (B) is from 10 to 30 mass%.
摘要:
To provide a water/oil repellent composition which is capable of imparting sufficient dynamic water repellency to the surface of an article, has high stability of the particles of the copolymer, and presents a low environmental impact, a method for its production, and a method for treating an article. A water/oil repellent composition comprising a copolymer (A) having structural units based on a monomer (a) having a C 1-6 polyfluoroalkyl group, structural units based on a (meth)acrylate (b) having a Z20-30 alkyl group and structural units based on a halogenated olefin (c), a surfactant (B), and a medium (C), wherein the medium (C) comprises water and a propylene glycol type solvent, and the amount of the propylene glycol type solvent is from 35 to 80 parts by mass per 100 parts by mass of the copolymer (A).
摘要:
A method is disclosed for strengthening a paper or textile article. The method involves (a) applying to the article a solution of an amorphous fluoropolymer in a perfluoroalkane solvent; and (b) drying the article. Also disclosed are strengthened paper and textile articles which include a fibrous paper or textile substrate, and amorphous fluoropolymer interconnecting fibers of the substrate.
