ABSTRACT:
Fire resistant glass fiber products are produced by coating the glass fibers with at least one nitrogen containing compound and at least 10 weight percent of at least one boron containing compound, drying the glass fibers and curing a binder that is in the coating. The nitrogen containing compound(s) are present in sufficient amounts that there is at least one mol or atom of nitrogen present for each mol or atom of boron present in the boron containing compound(s). When the product is exposed to a fire or high temperatures, such as about 1000 degrees F. or higher, the nitrogen released from the nitrogen containing compound(s) reacts with boron or boron oxide to form a sheath of refractory material around the fibers that protects the fibers and allows the fibers to maintain integrity to higher temperatures and/or for longer times than untreated fibers.
