Over ten million kilograms of gums ( guar, locust bean, and tamarind seed gums) are used annually by the paper industry as wet and additives. The gum is added to the pulp suspension at the suction side of the pulp suspension at the suction side of the fan pump just before the sheet is formed on either a fourdrinier or cylinder machine. Along with the lignin removed in the pulping process, much of the natural hemicelluloses (mannas and xylems) are removed.

Guar replaces and supplements these hemicelluloses in paper bonding with many advantages; 1. improved sheet formation with a more random distribution of pulp fibers ( less fiber bundies.) 2. Increased mullen or burst strength. 3. increased fold strength. 4. Increased tensile strength. 5. Increased pick. 6. Increased flat crush of corrugating medium. 7. Increased machine speed. 8. increased retention of fines. 9. Improved Finish. 10. Decreased porosity. The hydrogen-bonding effect is one of the major factors affecting fiber to fiber bonding. The rigid molecular structure of guar with its primary and its cis-secondary hydroxyl groups contributes to its interaction with the cellulose fibers in counteracting the fiber's natural tendency to lie in a machine oriented pattern.

This same hydrogen-bonding action is utilized with the hydrated mineral surface of the clay, talc, or shale. Guar acts in froth flotation and potash as an auxiliary reagent, depressing the gangue material. Guar is used as a setting agent to speed the settling of suspended solids in slimes and tailing from ore beneficiation. The separated water is then recycled. Guar is added to slime or clay pulp causes coagulation and allows faster filtration since the filter screen is no longer blinded by small particles.

Guar is used to prevent frozenpie filling from dehydrating, shrinking, and cracking. It is used in icings for its water-binding properties.

Guar is used as binder for fragmented tobacco fines to produce reconstitute Tobacco sheets. These flexible sheet with tensile strength and thickness of leaf tobacco, are blended with leaf tobacco, and retain the taste, flavor and aroma of an all-leaf product. Sheets are formed by passing a moist mixture of guar humectant, and tobacco fines between closely spaced steel rollers revolving at different peripherals speeds.

Guar Gum derivatives are used as print-paste thickeners. These derivatives are also used in roller and screen printing, as well as finishing agent. They are more economical than locust bean gum derivatives.
