Hydroxypropyl Starch Ether, also known as HPS or Starch Ether, is a modified starch that is derived from corn, potato, cassava, or wheat. It is produced by introducing a hydroxypropyl group to the starch molecule, which enhances its water solubility, stability, and performance. HPS is a white, odorless, and tasteless powder that has a pH range of 5.5-7.5.

HPS has several properties that make it an ideal additive for building materials. These properties include:
Water retention: HPS has excellent water retention properties, which helps to reduce cracking, shrinkage, and improves strength and durability of the finished product.
Thickening: HPS can increase the viscosity of building materials, which improves their workability and enhances adhesion to substrates.
Binding: HPS can act as a binder between different materials and improve their bonding strength.
Anti-slipping: HPS can prevent the sedimentation of particles in construction materials such as mortar and cement, thereby stabilizing the mixture and enhancing its performance.
Improved workability: HPS improves the texture and workability of building materials, making them easier to apply and spread.
Reduced water demand: HPS reduces the water demand of building materials, which can lead to cost savings and improve the properties of the final product.
Enhanced durability: HPS improves the strength, durability, and resistance to wear and tear of building materials, which increases their lifespan and reduces the need for repairs.
Enhanced adhesion: HPS improves the adhesion of building materials to substrates, which reduces cracking and enhances their structural integrity.
HPS is used as an additive in the making of various building materials such as plaster, concrete, mortar, grouts, and adhesives. It is added to the mixture during the production process as per the manufacturer’s instructions. The recommended dosage of HPS varies depending on the type of building material and its intended use. Some of the common uses of HPS in building materials include:
As a thickener and water retention agent in plaster
As an anti-slipping agent in mortar
As a rheology modifier in cement-based products
As a binder in grouts and tile adhesives
Hydroxypropyl Starch Ether is a versatile additive that has become an essential ingredient in the making of building materials. Its unique properties such as water retention, thickening, and binding make it an ideal ingredient that enhances the performance and quality of construction materials. HPS is being widely used in the construction industry and its demand is only growing. As research and innovation continue, we can expect to see more applications of HPS in building materials, further optimizing their performance and benefits.
