Product Q&A

Q:What is HPS used for?

HPS is a modified starch ether used as a thickener, water-retention agent, and rheology modifier. It is widely used in tile adhesives, putty, self-leveling compounds, and various dry-mix mortars.

Q:How does HPS compare to HPMC?

HPS is more cost-effective than HPMC while providing similar water retention and thickening properties. It offers better anti-sagging performance but slightly lower water retention at very high dosage. HPS can be used as a partial replacement to reduce costs.

Q:What is the recommended dosage?

Typical dosage is 0.2%-1.0% of total formulation. For tile adhesives, 0.3%-0.6% is common. For putty, 0.3%-0.5%. Specific dosage depends on application requirements and formulation.

Q:Does HPS dissolve well in water?

Yes. It dissolves easily in cold water without heating. Proper stirring ensures quick and uniform dissolution. It forms clear and stable solutions ready for use.

Q:Can HPS be used for outdoor applications?

Yes. It provides good water resistance and durability for outdoor construction applications. However, high-temperature stability may be lower than cellulose ethers. For extreme conditions, testing is recommended.
