What is Cold-Water Soluble HPMC?

Cold-water soluble hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether modified through a special process. It can be rapidly dispersed and dissolved in cold water at 5–25°C, significantly improving dissolution efficiency and applicability in construction.

This product possesses the following core characteristics:

Rapid Dissolution: Dissolves rapidly in cold water, significantly reducing stirring time and improving construction efficiency.

High Viscosity and Stability: The aqueous solution has a wide viscosity range and maintains stable performance within a pH range of 3–11, making it suitable for various cement-based and chemical environments.

Thermotropic Gel Behavior: Reversibly forms a gel at high temperatures (approximately 60–80°C), and recovers its flow dynamics upon cooling, helping to delay early hardening of the material during high-temperature construction in summer.

Optimized Construction Performance: It has good water retention and thickening effects, effectively extending open time, enhancing wet adhesion, and improving workability.

Cold water-soluble HPMC is widely used in tile adhesives, cement mortars, water-based coatings, and daily chemical products. While improving workability and finished product quality, attention should be paid to dosage control to avoid excessive dosage causing strength loss or air bubble problems.
