Self-Leveling Compounds Additives
What are Self-Leveling Compounds？
| Name | Cement-based self-leveling compounds | Gypsum-based self-leveling compounds |
|---|---|---|
| Components | Special cement, fine aggregates, binders, and various additives | High-strength gypsum, aggregates, and additives |
| Characteristics | High hardness, good wear resistance, environmentally friendly, good adhesion | High strength and stability, no hollowing, no cracking, and high levelness |
| Application Scenarios | Underground parking lots, production workshops, etc. | Indoor floor leveling like homes, hospitals, schools |
Both self-leveling compounds contain various additives with different functions, which enable self-leveling compounds to hold intensified development strength, better fluidity, and prolonged durability. LANDU, a large mature specialty chemicals manufacturer, provides qualified and environmentally friendly additives, ensuring the compounds perform robust bonding strength and strengthened wearproof ability.
What are Additives in Self-Leveling Compounds Formulas？
Common additives used for self-leveling compounds include water retainer, binder, defoamer, water reducer, and more. With several different brands under LANDU, we are aiming to provide you with a comprehensive chemical additives portfolio to consolidate your self-leveling compounds.
LANDU Additives - Optimize Your Self-Leveling Compounds
LANDERCOLL Cellulose Ethers for Self-Leveling Compounds
ACCURATE Redispersible Latex Powder for Self-Leveling Compounds
NOVASTAR Additives for Self-Leveling Compounds
As a great innovation of LANDU, NOVASTAR develops diverse chemical additives. NOVASTAR additives for self-leveling compounds include Polycarboxylate Superplasticizer and Powder Defoamer. They can significantly improve the fluidity and fluidity retention of self-leveling mortar, and enhance its slump retention. At the same time, they can also reduce the bleeding phenomenon and ensure a smooth and beautiful surface after leveling.
Key Additives in Cement-Based Self-Leveling Compounds
Providing PCE powder and PEC flakes for many partners worldwide, NOVASTAR polycarboxylate superplasticizer ensures cement-based self-leveling compounds have excellent rheology under the condition of a low water-binder ratio and have good cohesiveness under the premise of high fluidity, preventing bleeding and segregation. It can significantly reduce the shrinkage rate of the system, keeping it in a slightly expanded state in most cases, thereby reducing the occurrence of engineering accidents of self-leveling products.

LANDU LANDERCOLL Hydroxypropyl Methyl Cellulose(HPMC) is a non-ionic cellulose ether with high water retention capacity. It can delay water evaporation of cement-based self-leveling compounds, and thereby extend the construction operation time. This feature ensures operability and helps to achieve a higher level of construction flatness. By forming a protective film and enhancing the cohesiveness of the compounds, HPMC can reduce shrinkage cracks during the drying process, thereby improving the overall durability of the material.
Advantages
- Excellent Thickening Effect
- Enhanced Water Retention
- Extended Open Time
- Reduced Risk of Cracking
- Smooth Surface Finish

Key Additives in Gypsum-Based Self-Leveling Compounds
LANDU NOVASTAR Polycarboxylate Superplasticizer, also called water reducer, is an important additive used in gypsum-based self-leveling compounds. It can significantly enhance the fluidity of the mortar, making it more suitable for self-leveling construction. By altering the properties of the solid-liquid interface, it helps to release the water encapsulated by gypsum, thereby reducing the water requirement of the mortar. Besides, it also involves the synergistic effect of electrostatic repulsion and steric hindrance, which helps prevent direct contact between gypsum particles, forms a stable isolation film, and further improves the working performance of mortar.
Advantages
- Improved Fluidity
- Low Dosage, High Water Reduction
- Reduced Shrinkage
- Enhanced Overall Performance
| Product | Suggested Dosage | More |
|---|---|---|
| Polycarboxylate Superplasticizer 570P | 0.2–0.6% | Download TDS |
