Extend the construction operation time! HPMC Ensures Effortless Application of Self-Levelling Compounds

1. Do You Understand the Importance of the Application “Construction Window Period”?

In flooring works, the open time of self-levelling mortars is one of the key indicators determining overall construction quality. The term “Extend the construction operation time” refers to the Construction Window Period during which the mixed material retains good workability and flow.

If the operation time is too short, operatives will struggle to complete levelling and spreading within the designated timeframe. This can easily result in defects such as blistering, ridges, segregation, and uneven surfaces, and in severe cases may even lead to large-scale rework.

In high temperatures and low humidity, water loss from the material accelerates, exacerbating these issues. Therefore, incorporating components capable of effectively extending the open time has become an essential means of enhancing product competitiveness.

Tianyi New Material HPMC (Hydroxypropyl Methyl Cellulose), as a high-quality cellulose ether additive, plays an irreplaceable role precisely in this regard.

2. Tianyi New Material HPMC: Rising to the Time Challenge in Self-Levelling

Tianyi New Material HPMC offers outstanding water retention and rheology control. By forming a stable network structure within cement mortar, it significantly extends the open time of self-levelling mortars by over 30%.

This means operatives have more time to adjust the levelling process, ensuring every inch of flooring achieves optimal flatness and density.

Specifically, Tianyi New Material HPMC delivers the following benefits within the system:

• Delays cement hydration rate: Moderately slows the reaction between cement and water, preventing the surface from hardening prematurely;

• Locks in moisture and prevents rapid evaporation: Forms a hydration film that reduces water loss, maintaining good workability even in high temperatures;

• Regulates flow and thixotropy: Imparts different flow behaviours during mixing and resting, making it easy to spread while preventing excessive flow that causes unevenness.

This combination of effects makes Tianyi New Material HPMC an indispensable functional additive in flooring materials.

3. More Than Extended operation Time: Comprehensive Performance Enhancement

Tianyi New Material HPMC not only resolves the issue of short open time but also delivers significant improvements to overall performance, fully optimising the self-levelling experience:

• Improves application and levelling: Balances flowability and adhesion, enabling mortars to spread smoothly and self-level with minimal manual intervention;

• Enhances substrate bonding strength: Cellulose molecules penetrate the mortar–substrate interface, increasing overall adhesion and preventing delamination and debonding;

• Reduces bleeding and settlement: Increases viscosity and creates a stable gel structure, preventing cement particles from settling and maintaining uniformity;

• Adaptable to challenging climates: Maintains consistent water retention and workability even in hot, dry, or windy conditions, confidently handling summer and seasonal transitions;

• Environmentally friendly and safe: Produced using sustainable, eco-friendly processes that meet EU and Chinese green building standards, posing no risk to people or the environment.

Thanks to this multi-dimensional performance, Tianyi New Material HPMC has been widely applied in various flooring projects.
