Abstract
The present invention provides stable 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 fatty acid, an acid functional fatty acid ester, an acid functional fatty acid ether, or an inorganic stabilizer chosen from a mineral acid, a mineral acid amine or ammonia salt, and a Lewis acid, and mixtures thereof. The compositions can be used to provide binders for substrate materials including, for example, glass fiber.
