Starch Ether (HPS)

Chuangsha Dry Mix Additive - Starch Ether (HPS)

Chuangsha Dry Mix Additive - Starch Ether (HPS) is a construction additive based on hydroxypropyl starch ether, used to improve the performance of dry mix mortar, cement-based materials, and gypsum-based systems. This product functions as a rheology modifier, thickener, and anti-sagging additive that helps improve mixture consistency, workability, application stability, and slip resistance on vertical surfaces. With effective performance at low dosage levels, Chuangsha Starch Ether (HPS) supports dry mix formulations that are easier to apply, more stable, and capable of producing smoother finishes.

Starch Ether (HPS) is a dry mix additive that helps control rheology and mortar structure. In construction applications, HPS improves anti-sagging performance, slip resistance, thickening effect, and application stability, preventing mortar from sliding or sagging after being applied to vertical surfaces. It is also compatible with other additives such as cellulose ether, redispersible polymer powder, and superplasticizer in modern dry mix formulations.

In applications such as tile adhesives, wall putty, skim coats, gypsum plaster, cement-based mortar, and joint compound, Starch Ether (HPS) helps improve ease of application, reduce segregation, improve consistency, and support a smoother and more stable finish. It is especially useful for formulations that require a balance between easy troweling, shape stability, and anti-slip performance.
