Features & Benefits

· HSC-1781 has excellent workability, very good open time, excellent thermal stability, less retardation of cement hydration and excellent slip resistance.

· HSC-1781 also exhibits good workability and enhances water retention. The selected particle size distribution guarantees quick or lump free dissolution. It is compatible with all conventional mineral and organic binders.

· HSC-1781 is intended for dry mixing with other powder materials and should not be used for directed dissolving in water.

Packaging and Storage

· HSC-1781 is packed is packed in multiply paper bags with polyethylene inner liner of 25kg net. We recommend emptying the bags from the bottom. The empty bags can be recycled or burned

· HSC-1781 is a non-perishable product. It is recommended to use the product in rotation on a first-in first-out basis. The product should be stored under dry and clean conditions in its original packing and away from heat. The product is hygroscopic. The packaging is selected in a way to avoid ingress of moisture, but the water content of the packed product will/may increase if not stored dry.

· When stored in closed containers, or in its original packaging in a dry place at room temperature, it can be kept for a long time. In the case of high viscosity grades, a slow loss of viscosity can be measured after long-term storage (>1 year). It absorbs water from moist air. Once opened, package must be resealed and kept tightly closed.

Scope of Application

HSC-1781 was developed for cement-based applications, like cement-based tile adhesives and Masonry Mortar.
