Abstract:
The present invention provides thermosetting aqueous binder compositions comprising one or more reducing sugar, one or more diprimary diamine or poly(primary amine), and from 7 to 45 wt.%, based on total solids, of one or more polysaccharide having a dextrose equivalent (DE) value of from 5 to 30. The compositions provide treated articles, such as fiberglass mat. The binders provide articles having a dramatically reduced binder weight loss upon cure and a reduction in cure energy needed to achieve early dry strength.
Abstract:
According to the present invention, water repellant curable compositions comprise: (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 C 5 to C 30 alk(en)yl 2-hydroxyethyl (alk(en))amide, C 5 to C 30 alk(en)yl bis(2-hydroxyethyl) amide, C 11 to C 30 alk(en)yl 2-hydroxyethyl (alk(en))amine, C 11 to C 30 alk(en)yl bis(2-hydroxyethyl) amine, C 11 to C 30 alk(en)yl tris(2-hydroxyethyl) amine, C 5 to C 30 alk(en)yl monoglyceride, C 5 to C 30 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. Further, the present invention 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, as well as water resistant products produced thereby.
Abstract:
The present invention provides thermosetting aqueous binder compositions of one or more cyclic enamine, including bis-enamines and di- or higher functional enamines, optionally containing a water soluble or dispersible or dispersible primary amine compound. The binders are at least substantially formaldehyde free, need no polycarboxylic or polycarboxylate component, and yet provide excellent hot wet tensile strength when cured for as little time as a minute or less in use.
Abstract:
A curable aqueous binder composition comprising one or more amine reactant selected from the group consisting of: a protein, a peptide, an amino acid, an ammonium salt of a polycarboxylic acid, an ammonium salt of a (poly)hydroxy-(poly)carboxylic acid; one or more carbohydrate; and one or more emulsion polymer; and the use thereof as thermosetting binders. Also described are composite materials comprising the curable binder composition, and methods of application.
