Description
Hydroxypropyl Starch Ether offers numerous advantages due to its unique properties, such as thickening in solution, excellent water solubility, stability in suspensions or glue solutions, colloid protection, film-forming ability, water retention, and bonding capabilities. HPA made by Sakchi Chem Sciences Pvt Ltd is designed from nontoxic compounds which are odorless and biocompatible.
It is extensively used in a wide range of cement and gypsum-based interior and exterior wall putty powders. It also works best for tile adhesives, stone binders, facing mortars, plastering mortars, and external wall thermal insulation systems. Beyond construction, it finds applications in building materials, detergents, textiles, papermaking, food, cosmetics, coatings, and various other industries.
In terms of its technical specifications, Hydroxypropyl Starch Ether is available in powder form and appears white. The pH of the powder ranges between 7 to 9 and has a moisture content of a maximum of 10%. The viscosity of this product ranges from 1200 to 1600 m.Pa.s.
It is advised to add HPS within a range of 0.05% to 0.15%. Accordingly, the amount of Hydroxy Propyl Methyl Cellulose (HPMC) in the original formula should be reduced by approximately 0.1% to 0.2%.
Hydroxypropyl Starch Ether is packaged in 25 kg bags and should be stored in a dry and cool place, protected from dampness, rain, sunshine, and fire. For best results, use the product within 12 months of delivery.
