Product Description Construction grade hydroxypropyl starch is the fastest growing industry in starch ether application industry. ZHUOJUN ZJ-HPS is a kind of ionic hydroxypropyl starch, which is produced by a series of chemical and physical reactions with starch as raw material. It is non-toxic, tasteless white or beige power, which can be dissolved in cold water to form transparent or translucent viscous liquid. It is effective in thickening, adhesion, dispersion, emulsification, suspension, adsorption, surface activity, water retention and so on. And it is well compatible with other additives in gypsum or cement based building materials. ZHUOJUN ZJ-HPS can be applied in following construction materials: - Cement and gypsum based mortars - Tile adhesives - Joint filler and crack filler ZHUOJUN ZJ-HPS Advantages: Improve the performance and workability of dry mortar Improve adhesion strength Excellent performance in neutral and alkaline conditions Good solubility in cold water with stable transparent and colorless solution Well compatible with other additives Cost-effectiveness Technical Data for ZJ-HPS Model No.ZJ-HPS Appearancewhite or beige power Particle Size (%, 100 mesh passing rate)98.5% SolubilitySoluble in cold water Water Content (%)â?¤14 Hydroxypropyl Content (%)20-40 pH Value (1% aqueous solution at 25) 5-11.5 Viscosity (mPa's, 5% aqueous solution at 20) 100 Packaging A.Standard packed in 25 KG per paper plastic composite bag B.Big bags or other special packages are possible on request Storage Stored in its original packaging in dry place Warranty It is recommended to use ZHUOJUN HPS within 12 months.
