The working principle of HEMC powder
1. Water solubility and thickening property:
can form a transparent colloidal solution in water, significantly increasing the viscosity of the system, and is suitable for scenarios requiring control of fluidity (such as coatings, adhesives).
2. Water retention capacity:
In building materials (such as cement mortar), HEMC can slow down the rate of water evaporation, ensure complete hydration of the material, and enhance strength and crack resistance.
3. Thermogel property:
When the temperature rises to a specific critical point (usually 40-60℃), the HEMC solution will temporarily gel, and regain fluidity after cooling. This property is used in food industry for temperature control processes.
4. pH stability:
It maintains stable performance within the pH range of 3-11, suitable for formulation design in acidic and alkaline environments.
Main Application
01 Construction Materials Field
Dry-mixed Mortar: As a water-retaining agent and thickening agent, HEMC can improve the workability and anti-sagging property of the mortar, and reduce the problems of hollowing and cracking.
Self-leveling Floor Materials: By adjusting the viscosity, it ensures the uniform flow of the slurry and extends the operational time.
02 Coatings and Adhesives
Latex Paint: HEMC provides excellent opening-cup performance and smooth application, preventing pigment sedimentation.
Tile Adhesive: Enhances the wetting property of the adhesive to the substrate, improving the bonding strength.
03 Medicine and Cosmetics
Drug Sustained-release Agent: As a coating material for tablets, it controls the release rate of the drug.
Personal Care Products: Used in shampoos and toothpaste, it improves texture and suspension stability.
Product Advantages of HEMC

- •Solubility:
HEMC dissolves faster in cold water, while HPMC requires a higher temperature. - •Gel temperature:
The gel temperature of HEMC is usually lower than that of HPMC, making it suitable for environments requiring low-temperature construction. - •Biodegradability resistance:
Due to the presence of hydroxyethyl groups, HEMC has slightly better mold resistance than HPMC.
