MT1004 self leveling

A). Overview of Self-Leveling Compounds (SLC)

Self-leveling compounds (SLC) are advanced cementitious mortars composed of cement, sand, and specialized chemical additives. These materials are widely used in flooring applications where a smooth, even surface is required. Their key characteristics include:

• Excellent fluidity, ensuring smooth self-leveling performance.
• Rapid curing, reducing project downtime.
• Thin-layer application, minimizing material consumption.
• Environmental friendliness, as they mainly consist of inorganic materials.

Selecting the right self-leveling cement additive and formulation plays a crucial role in achieving durable and high-performance self-leveling mortar. Celotech offers advanced cellulose ether solutions tailored to improve self-leveling floor applications.

B). Application of Low Viscosity Cellulose Ether in Self-Leveling

Hydroxypropyl methylcellulose (HPMC) for self-leveling applications is an essential additive in modern construction. The addition of water-retaining HPMC for smooth self-leveling floor applications significantly improves workability and overall floor quality by:

• Enhancing water retention, preventing excessive bleeding and ensuring proper hydration of cement.
• Improving surface strength, minimizing cracks and shrinkage.
• Increasing viscosity control, optimizing material flow and reducing sedimentation.

Celotech’s HPMC self-leveling stabilizer, such as Celopro® MT1004, is specially designed to optimize the formulation of self-leveling cement.

C). Common Issues in Self-Leveling Compounds

1. Sand Sedimentation and Bleeding

• Poor suspension properties can lead to sand settlement and water bleeding, affecting the final floor finish.
• Excessive bleeding weakens the structure, increasing the risk of cracks, delamination, and hollow spots.

2. Shrinkage Differences Leading to Cracking

• Low sand-content cement results in high shrinkage, increasing crack formation.
• High sand-content cement has lower shrinkage, improving overall stability.
• Significant shrinkage variation between layers increases the risk of surface cracks after curing.

3. Bleeding and Surface Quality Defects

• Excessive water bleeding leads to poor adhesion strength and a weak top layer.
• Uneven curing causes surface dusting, reducing durability.

D). Solution: HPMC Celopro® MT1004 for High-Performance Self-Leveling Mortar

To counter these common issues, Celotech provides Celopro® MT1004, a high-performance self-leveling compound additive with the following benefits:

• Optimized low-viscosity HPMC, specifically designed for self-leveling cement applications.
• Enhanced suspension properties, effectively preventing sand settlement.
• Superior anti-bleeding performance, ensuring a uniform and smooth finish.

1. Technical Parameters

• Model: Celopro® MT1004
• Viscosity: 400 mPa•s (Brookfield, 2%, 20℃)
• Main Function: Stabilizer, preventing sand sedimentation and water bleeding.

2. Suspension Performance Test

Tests comparing different formulations show that Celopro® MT1004 significantly improves suspension properties. Samples using Celopro® MT1004 exhibit uniform sand distribution, whereas standard HPMC formulations often result in noticeable sedimentation.

Note: Right side is Celopro® MT1004, left side is Market HPMC.

Celopro® MT1004 has a very good suspension effect with sand, so it has a better anti-sand settlement effect in SLC.

3. Self-Leveling Compound Performance Comparison

Wet Flow Performance

• Celopro® MT1004 (27% & 28% water content, left): Provides superior flowability and consistent texture.
• Market HPMC (right): Shows reduced flow performance and uneven distribution.

Surface Quality After Curing

• Celopro® MT1004 (27% & 28% water content): Produces a smooth and even self-leveling floor finish.

• Market HPMC (27% & 28% water content): Results in a rough, porous surface, reducing strength and aesthetics.
