Hydroxypropyl Starch Ethers HPS for Bond Mortar Admixtures
HYDROXYPROPYL STARCH [HPS]
HPS Overview
Hydroxypropyl starch ether HPS is an ionic starch ether produced by a series of chemical and physical reactions under alkaline conditions using natural polymer material-starch as raw material. Hydroxypropyl starch ether is a non-toxic, odorless, irregular phosphor or white powder that can be dissolved in cold water to form a transparent or translucent viscous liquid. It has the properties of thickening, bonding, dispersing, emulsifying, suspending, adsorbing, surface active, and retaining moisture.
Starch ether HPS is a chemically modified starch ether that is soluble in water and can be used with dry powder mortar
Widely used in tile adhesives, repair mortar, plaster plaster, internal and external wall putty, gypsum-based caulking and filling materials, interface agents, masonry mortar.
The main characteristics of starch ether are: (1) Improve sag resistance; (2) Improve workability.
Specification
| Appearance | White or yellowish powder |
| Solubility | Soluble in cold water |
| Moisture Content | ≤ 5% |
| Ph (1% water solution, at 25℃) | 8-11.5 |
| Viscosity, mPa.s（ 5% water solution） | 400~1800 |
| Particle Size, mesh | 100mesh, ＞99% |
| Bulk Density, kg/m3 | 400-500 |
Dosage
①cement or gypsum based interior / exterior wall skim coat ② adhesive for tile or stocks ③ finishing mortar, plaster mortar, ETIFS. The dosage of HPS is about 1-2 kg/ton, based on the original formula, reduce the HPMC dosage about 1-2 kg/ton（save cost about 10%-20%）.
Package
N.W.: 25±0.25kg / bag; Inner: PE plastic film bag, Outer: PP woven bag;
Application
| Application | Performance |
| Interior/ Exterior Wall Skim Coat (Wall Putty, Lacquer Putty) | Thixotropy |
| Adhesive Mortar | Good Fluidity, Viscosity Stability |
| Gypsum Plaster | Rheology |
| Joint Filler | Sag Resistance, Viscosity Stability |
| ETIFS | Viscosity Stability |
