Low or free boron-containing glass fibers treated with amine functional organo silane coupling agents have a decreased performance in conforming to mold configurations over fibers having conventional amounts of boron and treated with aminefunctional organo silane coupling agents. The low or free boron-containing glass fibers treated with an amine functional organo silane coupling agent are also treated with a softening agent in an effective softening amount to overcome the additional brittleness. The softening agent in conjunction with the amine functional organo silane coupling agent provides a moisture-reduced residue on the glass fibers where the residue has a glass transition temperature of less than 30°C. The chemical treating composition can also have one or more film forming polymers, one or more lubricants, and one or more additional coupling agents. The film forming polymer has a glass transition temperature in the range of around 30°C to -20°C.
