| 摘要 |
The present invention provides water repellant curable compositions comprising (i) one or more polyacid comprising at least two carboxylic acid groups, anhydride groups, or salts thereof, (ii) one or more polyol comprising at least two hydroxyl groups, (iii) one or more reactive waterproofing agent chosen from a C5 to C30 alk(en)yl 2-hydroxyethyl (alk(en))amide, C5 to C30 alk(en)yl bis(2-hydroxyethyl)amide, C11 to C30 alk(en)yl 2-hydroxyethyl (alk(en))amine, C11 to C30 alk(en)yl bis(2-hydroxy-ethyl)amine, C11 to C30 alk(en)yl tris(2-hydroxyethyl)amine, C5 to C30 alk(en)yl monoglyceride, C5 to C30 alk(en)yl monocarboxylate of a trihydric polyol, and mixtures thereof, and, (iv), optionally, one or more phosphorous-containing accelerator, wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the total number of equivalents of said hydroxyl groups is from 1/0.01 to 1/3. The compositions provide concentrates dilutable with water to make thermosetting aqueous binder compositions for use in methods to treat or contact substrates chosen from a non-woven, woven and a composite, e.g. glass fiber substrates, followed by drying and curing.
