ABSTRACT:
According to the present invention, water repellant curable compositions comprise: (i) one or more polyacid; (ii) one or more polyol comprising at least two hydroxyl groups; (iii) one or more reactive waterproofing agent chosen from a C5to C30alk(en)yl monocarboxylate of a (poly)ethoxylated trihydric polyol, C5to C30alk(en)ylamine (poly)alkoxylate, C5to C30alk(en)yl diamine (poly)alkoxylate, C5to C30alk(en)ylamine (poly)alkoxylate containing an ether or thiother group in the alk(en)ylamine group, and mixtures thereof. The compositions are dilutable with water to make thermosetting aqueous binder compositions. The present invention also provides methods of treating or contacting substrates chosen from a non-woven, woven and a composite, such as glass fiber substrates, with the thermosetting aqueous binder compositions, and drying and curing, and the water resistant products produced thereby.
