The present invention relates to a glass fiber binding composition having an effective binding amount of an aqueous compatible furan resin mixed with sufficient water to result in a binding composition having from 0.5 to 80% nonvolatile. The aqueous compatible furan resin is the reaction product of a source of ammonia and a first reaction product, the first reaction product being derived from the reaction of an acidic furan resin, a source of reactable formaldehyde, and a formaldehyde scavenger. The invention further pertains to a process of binding glass fibers at junctions of the fibers comprising the steps of providing glass fibers, applying an effect binding amount of the binding composition of the invention to the glass fibers such that the binder is present at a portion of the junctions, and curing the resin at the junctions of the glass fibers. Finally, the invention also discloses glass fiber compositions comprising a plurality of glass fibers having a plurality of junctions where two or more fibers meet, and an effective binding amount of the binding composition of the invention.
