Glass fiber binding compositions, process of making glass fiber binding compositions, process of binding glass fibers, and glass fiber compositions

A glass fiber binding composition, made by the process comprising the steps of:

• providing an effective binding amount of an acidic aqueous compatible furan resin;
• providing a source of reactable formaldehyde;
• mixing a formaldehyde scavenger with the furan resin in the presence of the source of reactable formaldehyde to form a first mixture;
• heating the first mixture to a temperature of less than 100 degrees C. for period of from 1 to 10 hours;
• adding a source of ammonia to the first mixture to form a second mixture;
• heating the second mixture to a temperature of less than 100 degree C. for a period of from 1 to 10 hours;
• and
• adding sufficient water to form a binding composition having from 0.5 to 80% nonvolatile.

A process of binding glass fibers comprising the steps of:

• providing glass fibers having a plurality of junctions;
• providing a glass fiber binding composition comprising:
• an effective binding amount of an aqueous compatible furan resin comprising the curable reaction product prepared by heating a source of ammonia sufficient to supply from about 1 to about 15 weight percent relative to resin solids and a first reaction product, said first reaction product comprising the reaction product of an acidic furan resin, a source of reactable formaldehyde and a formaldehyde scavenger;
• and
• a sufficient amount of water to result in a binding composition having from 0.5 to 80% non-volatiles;
• applying an effective amount of the binding composition to the newly formed glass fibers such that binder is present at a portion of the junctions;
• and
• curing the binder.
