Procedure

The present application is further directed to a method of making a binder. Guar gum with water at a temperature in excess of 145° F. to form a guar gum-water mixture. The guar gum-water mixture is cooled to approximately 135-145° F. Ammonium sulfate and water are added to the guar gum-water mixture to form an ammonium sulfate-guar gum-water mixture. The temperature of this mixture is less than or equal to 145° F. Urea is mixed to the ammonium sulfate-guar gum-water mixture to form a urea-ammonium sulfate-guar gum-water mixture. Water and methyl acryloid are then added to the urea-ammonium sulfate-guar gum-water mixture to form the binder.
