Abstract
An aqueous binder composition comprises: (1) a water-soluble binder component obtainable by reacting at least one alkanolamine with at least one polycarboxylic acid or anhydride and, optionally, treating the reaction product with a base; (2) a soy protein product; and, optionally, one or more of the following binder components; (3) a sugar component; (4) urea. The binder composition is particularly suitable as a binder for mineral fibres or as an adhesive for particle board and other composites.

-13. (canceled)
An aqueous binder composition comprising:
- (1) a water-soluble binder component obtainable by reacting at least one alkanolamine with at least one polycarboxylic acid or anhydride and, optionally, treating a resultant reaction product with a base;
- (2) a soy protein product;
- and, optionally, one or both of:
- (3) a sugar component;
- (4) urea.
An aqueous binder composition comprising:
- from about 10 to about 50 wt. % of (1) a water-soluble binder component obtainable by reacting at least one alkanolamine selected from monoethanolamine, diethanolamine, triethanolamine, diisopropanolamine, triisopropanolamine, methyldiethanolamine, ethyldiethanolamine, n-butyldiethanolamine, methyldiisopropanolamine, ethylisopropanolamine, ethyldiisopropanolamine, 3-amino-1,2-propanediol, 2-amino-1,3-propane-diol, aminoethylethanolamine, and tris-(hydroxymethyl)-aminomethane with at least one polycarboxylic acid or anhydride selected from at least one of tetrahydrophthalic acid, hexahydrophthalic acid, methyltetrahydrophthalic acid, phthalic acid, methylphthalic acid, trimellitic acid, pyromellitic acid, and corresponding anhydrides and, optionally, treating a resultant reaction product with a base;
- from about 50 to about 90 wt. % of (2) a soy protein product;
- (3) a sugar component which is a reducing sugar having a dextrose equivalent (DE) of from 40 to 100;
- and, optionally,
- (4) urea.
