Guar gum is a natural hydrocolloid derived from the seeds of the guar bean, and is a sustainable, renewable, environmentally friendly resource with a wide range of uses. Hydroxypropyl guar (HPG), also known as guar ether, 2-hydroxypropyl ether, guar 2-hydroxypropyl ether, or propoxylated guar, is produced by an etherification reaction in which guar gum is chemically modified with a nonionic propylene oxide reagent. The resulting product, hydroxypropyl guar, is a material with a wide range of uses.
In agriculture, it can be used as an inert thickener in pesticide formulations. In the food industry, it is approved as an indirect food additive. It is also used as a sizing agent in textiles, a rheology modifier in oil drilling, and a paper properties enhancer in papermaking.

1. Workability
Exhibits pseudoplastic rheological behavior:
At low shear rates, viscosity is comparable to cellulose ethers.
At high shear rates, viscosity decreases significantly, enhancing the mortar’s workability and providing a smooth surface.
Improves adhesion and stability in wet systems without negatively affecting consistency or water retention, ensuring excellent workability and a perfect finish.
2. Water Retention: It offers excellent water retention due to adequate molar substitution. Enhances binder setting and reduces plastic shrinkage.
3. Consistency: Improves mortar consistency, preventing sagging in plaster and tiles when applied to vertical surfaces.
Packed in 25 kg multilayer paper sack with polyethylene intermediate layer and inner P.E. bag.It is recommended that it be kept sealed and away from moisture. Do not expose it to direct sunlight or near fire sources.
