The main properties of HPMC related to cement binders

The water-holding capacity of HPMC is critical for cementitious binders. It helps prevent premature drying, allows the cement particles to properly hydrate, and ensures a strong bond between the adhesive and the substrate.

Thickening and Rheology Control:

As a thickener, HPMC helps improve the viscosity and rheological properties of adhesives. This is essential to achieve correct consistency and workability, promote ease of application and reduce the risk of sag.

Improved adhesion:

HPMC enhances the bonding properties of cementitious adhesives, promoting better bonding to a variety of substrates. This is particularly important for applications requiring reliable and long-lasting bonding.

Set time control:

The addition of HPMC can control the setting time of cementitious binders. This is advantageous in different construction scenarios where setting time needs to be adjusted to meet specific requirements.

Extended opening hours:

Open time refers to the duration that an adhesive remains usable after application. HPMC has extended opening hours to provide workers with flexibility and ensure adequate time for proper placement and adjustments.

Improve cohesion:

HPMC helps improve the cohesion of cementitious binders, preventing them from cracking or cracking. This is particularly important in applications where the adhesive layer needs to withstand stress over time.
