Starch Ether for Mortar

Starch ether, also known as hydroxypropyl starch ether(HPS). It has excellent water retention capacity, thickening properties, and good adhesion characteristics. Starch ether has become a preferred choice for improving mortar performance.

 

WOTAIchem is a good source of high-quality HPS powder. We’re here to help you achieve better construction work.

 

WOTAIchem’s HPS powder is not only for mortar but also for wall putty and adhesives. If you need formula support, our OEM team will be ready to assist you.

Main Benefits of Starch Ether for Mortar

As one of the rheology modifiers, starch ether provides significant benefits to various building materials, especially mortar. It effectively improves the rheological properties. Starch ether can address the issues of flow and sag in building mortar. Starch ether can enhance water retention and prolong the open time of the mortar.

Dry Mortar VS Wet Mortar

Dry mix mortar Wet mix mortar
Dry mix mortar is suitable for more delicate projects such as grouting, tile repair, reinforcing or repairing concrete. Wet mix mortar is usually better for more extensive projects created from scratch, such as house building.
Storage time: Storage time:
Dry mix versions are only mixed when required. Offering greater flexibility in terms of storage, large quantities can be stockpiled. Wet mixes already contain water, as a matter of fact, they need to be used within 24 hours of the mixture being affected.
Equipment and site requirements: Equipment and site requirements:
Dry mix mortar requires application equipment that mixes the dry material with water at the construction site. An ideal option for small to medium-sized projects in delicate concrete where workers have better control. Wet mixing mortar requires more space on the construction site. So trucks can access and deliver the concrete material, making it more suitable for larger projects.

 

The 5 Major Hydroxypropyl Starch Ether Uses

Starch Ether for Mortar

Plastering Mortar

Starch ether acts as a rheology modifier in plastering mortar. It enhances workability, cohesion, and sag resistance.

 

By incorporating starch ether, the mortar is much easier to spread. It also improves the adhesion to the substrate. Resulting in a smoother and more durable plaster finish.

Can starch ether be used in combination with other additives?

Certainly! Starch ether is a water-soluble chemically modified starch ether compatible with other dry mortar additives. It can be easily combined with other additives, such as air entrainers or superplasticizers to achieve the desired properties in mortar.

Additionally, the incorporation of starch ether allows for a reduction in the dosage of cellulose ethers by approximately 0.05% – 0.1%.

What is dry mix mortar used for?

Dry mix mortar is suitable for more delicate projects such as grouting, tile repair, reinforcing or repairing concrete.

Is starch ether compatible with different types of cement?

Starch ether shows good compatibility with various cement types, including Portland cement, blended cement, and specialty cement formulations.
