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 Cto Calk(en)yl 2-hydroxyethyl (alk(en))amide, Cto Calk(en)yl bis(2-hydroxyethyl)amide, Cto Calk(en)yl 2-hydroxyethyl (alk(en))amine, Cto Calk(en)yl bis(2-hydroxy-ethyl)amine, Cto Calk(en)yl tris(2-hydroxyethyl)amine, Cto Calk(en)yl monoglyceride, Cto Calk(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.

Water repellant curable aqueous compositions

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 Cto Calk(en)yl monocarboxylate of a (poly)ethoxylated trihydric polyol, Cto Calk(en)ylamine (poly)alkoxylate, Cto Calk(en)yl diamine (poly)alkoxylate, Cto Calk(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.

A curable aqueous composition including (a) a polyacid including at least two carboxylic acid groups, anhydride groups, or salts thereof; (b) a polyol including at least two hydroxyl groups; and (c) an emulsion polymer including, as copolymerized units, greater than 30% by weight, based on the weight of the emulsion polymer solids, ethylenically unsaturated acrylic monomer including a Cor greater alkyl group; wherein the ratio of the number of equivalents of the carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of the hydroxyl groups is from 1/0.01 to 1/3, and wherein the carboxylic acid groups, anhydride groups, or salts thereof are neutralized to an extent of less than 35% with a fixed base is provided. Also provided is a method for treating heat-resistant fibers or a heat-resistant nonwoven formed therefrom with the curable aqueous composition and the article prepared thereby.

Curable aqueous composition and use as heat-resistant nonwoven binder

A composition including two components is provided. When the two components are admixed in the method of the invention a polymer-modified gypsum composition is provided. The admixture exhibits a useful balance of setting time and stability.

Polymer-modified gypsum composition

A fast drying traffic paint which includes at least 0.1% by weight, based on the weight of the paint composition, of fibers is disclosed. The paint exhibits reduced cracking during drying. A method for reducing the degree of surface cracking in a fast drying traffic paint during drying is also disclosed. The method comprises incorporating into the paint at least 0.1% by weight, based on the weight of the paint composition, of fibers. Use of at least 0.1% by weight, based on the weight of the paint composition, of fibers in a fast drying traffic paint to reduce the degree of surface cracking during drying of the paint is also disclosed.
