HPS (Hydroxypropyl Starch)
HPS is characterized by excellent thixotropy and workability enhancement—effectively improving the spreading performance of mortars, reducing water loss in thin-layer constructions, and optimizing the cohesive force of fresh mortars without significantly increasing viscosity, making it ideal for tile adhesives, wall putties and other construction mortars.

● Good Water Solubility: It can be dissolved in cold water to form a transparent or semi-transparent viscous liquid.
● Water Retention: HPS can retain water to a certain extent.
● Thickening and Rheology Modification: HPS increases the viscosity of the mortar, imparting a cohesive and non-fluid consistency.
● Enhanced Workability and Lubrication: HPS creates a lubricating effect within the mortar mix. This makes the material easier to trowel, spread, and manipulate.
● Superior Anti-Slip Resistance: HPS provides excellent anti-slip resistance, ensuring that tiles, for instance, do not slide down after application.
● Compatibility and Stability: HPS demonstrates good compatibility with other common additives in dry-mix mortar formulations. And it is stable to acids and alkalis.Packaging and Storage
Standard packing: 25kg/bag inner with PE bags
Should be stored in dry and cool environment.
lt's recommended to use within 2 years, storage in high humidity and temperature will increase the risk of blocking.
Storage under pressure should also be avoided.
Do not stack pallets on top of each other.
Practice care and caution to avoid explosive conditions.
