Hydroxypropyl Starch Ether (HPS) can be used sparingly while still achieving the desired results, making it a highly cost-effective product. HPS is water-soluble and provides excellent stability to adhesives and other suspension solutions.

Additionally, it protects colloids, retains water, and effectively forms a fine film upon drying. HPS can create strong bonds between various construction chemicals.

Moreover, Hydroxypropyl Starch Ether (HPS) is entirely non-toxic, odorless, and biocompatible, making it incredibly safe for use.

Applications of Hydroxypropyl Starch Ether (HPS)

Hydroxypropyl Starch Ether (HPS) is beneficial for:

• Interior and exterior wall putty
• Plastering mortar
• Facing mortar
• Tile binder
• External thermal insulation

Hydroxypropyl Starch Ether

Hydroxypropyl Starch Ether is a starch-based additive formulated for dry mortars in the construction industry, imparting unique properties to cement and gypsum-based products.

This ether, possessing a similar chemical structure to Hydroxypropyl Methylcellulose (HPMC), not only provides comparable functions but also ensures good compatibility with other building aids. When employed alongside Hydroxypropyl Methylcellulose (HPMC), Hydroxypropyl Starch Ether enhances thickening effects, yielding improved crack resistance and processability. It performs excellently in neutral and alkaline conditions, demonstrating compatibility with other additives in gypsum or cement-based materials. The overall cost of mortar formulations can be notably reduced through the addition of starch ethers.

Properties of Hydroxypropyl Starch Ether

Hydroxypropyl Starch Ether enhances sagging resistance through its anti-sagging properties, optimizing workability.

This product effectively prevents the draping phenomenon in thick mortar layers, addressing issues such as tile sliding and thick layer drape.

By adding an appropriate amount of Hydroxypropyl Starch Ether to the mortar, its opening time can be extended. The water retention of starch ethers remains stable even with rising temperatures. Therefore, this product not only enhances the water retention performance of the mortar but also compensates for the rapid loss of capacity typically experienced by ordinary water retention agents at elevated temperatures.

Additionally, Hydroxypropyl Starch Ether exhibits rapid thickening effects on mortar, improving the rheology of spray and plastering mortars.

This ether significantly prevents mortar delamination and segregation, making it suitable for use in self-leveling mortars. LEARN MORE
