Self-leveling Compounds
Self-Leveling Compounds, also known as Self-Leveling Underlayment, is a modern cementitious or gypsum-based material. Its key feature is high fluidity when mixed. After pouring, it flows easily to fill voids and irregularities under gravity, eliminating extensive manual smoothing and ensuring a uniform finish.
Critical to success is proper surface preparation: the substrate must be clean, sound, and primed to ensure adhesion. The material is mixed with precise amounts of water, poured, spread and de-aired with a tool. Then it self-levels to a smooth surface.
By incorporating FUQING HPMC and RDP into formulations, you can produce a premium self-leveling mortar that:
· Achieves a perfectly level surface.
· Reduces delamination risk and ensures durability.
· Withstands heavy loads and traffic.
· Forms a stable, long-lasting underlayment.
In summary, self-leveling mortar is essential in modern construction for creating level substrates quickly and efficiently.
What's our Product Effect?
1. Cellulose Ether (HPMC/MHEC)
FUQING cellulose ether acts as a crucial multifunctional additive.
It provides excellent water retention, ensuring complete cement hydration for optimal strength development and preventing premature drying.
Simultaneously, it enables precise viscosity control and thickening effect, which is crucial for achieving optimal flowability and preventing material segregation. This ultimately ensures consistent and uniform application.
2. RDP Powder (Redispersible Polymer Powder)
FUQING RDP powder, as a key ingredient in self-leveling mortar, significantly enhances the flexibility, adhesion strength, and abrasion resistance of the cured mortar.
By forming a polymer film within the matrix, RDP improves cohesion and bond to various substrates, reducing the risk of cracking and delamination. It also contributes to improved toughness and durability under mechanical stress.
Frequently Asked Questions
What is the key factor for achieving good self-leveling in compounds?
The key factor is controlled rheology—the compound should have low viscosity under shear to flow easily but high viscosity at rest to prevent segregation. Additives like PCE superplasticizers are crucial for achieving this balance.
Can MHEC be used in self-leveling compounds, and what is its role?
Yes, MHEC can be used as a viscosity modifier to prevent sedimentation and control flow. It helps maintain uniformity and reduces the risk of segregation during application.
What causes blistering or pinholes in self-leveling floors, and how can it be avoided?
Blistering is often caused by entrapped air, improper mixing, or rapid drying. Avoidance measures include using defoamers, ensuring thorough mixing, and applying the compound in a controlled environment with proper ventilation.
How can I ensure the durability of self-leveling compounds under heavy traffic?
Durability is ensured by using high-quality cement, additives like RDP for strength and flexibility, and proper curing. A well-designed mix with PCE for low permeability can withstand heavy loads and abrasion.
