A process for preparing binder-coated fiberglass products employs as a binder aqueous polymer systems comprising a nitrogenous formaldehyde resin such as a urea-extended alkaline phenol/formaldehyde resole together with an acidic polyacrylate which cocure to form a thermoset polymer while synergistically reducing ammonia emissions which normally occur during cure of the nitrogenous formaldehyde resin. The polymer system may be used in applications other than fiberglass where reduced emissions are desired.
