Abstract

The invention provides table aqueous thermosetting binder compositions having a total solids content of 15 wt.% or higher, preferably, 20 wt.% or higher, and having extended shelf life comprising one or more reducing sugar, one or more primary amine compound, and one or more stabilizer acid or salt having a pKa of 8.5 or less. The total amount of stabilizer used may range from 5 to 200 mole%, based on the total moles of primary amine present in the binder. The stabilizer may be an organic stabilizer chosen from a monocarboxylic acid, a dicarboxylic acid , a C<12>to C<36>fatty acid, an acid functional C<12>to C<36>fatty acid ester, an acid functional C<12>to C<36>fatty acid ether, or an inorganic stabilizer chosen from a mineral acid, a mineral acid amine salt, a mineral acid ammonia salt, and a Lewis acid, and mixtures thereof. The compositions can be used to provide binders which are water resistant and to make articles from substrate materials including, for example, glass, glass fiber, wood, or woody materials.
