Features & Benefits

· HSC-1785 has excellent workability, excellent thermal stability, and high adhesion strength. And it can improve the rheology of the plaster. 
· HSC-1785 also imparts 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.

Packaging and Storage

· HSC-1785 is packed in multiply paper bags with an inner polyethylene bag. Net weight 25kg. We recommend emptying the bags from the bottom. The empty bags can be recycled or burned. In unopened bags, HSC-1785 can be stored for several years. In opened bags, the moisture content of HSC-1785 will be influenced by the air humidity.
· 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 lengthy storage (>1 year). It absorbs water from moist air. Once opened, container must be resealed and kept tightly closed.

Scope of Application

HSC-1785 was developed cement based application, like tile adhesive, cement plaster, lime cement plaster, tile grout and EIFS/ETICS.
