Behind the high-efficiency application and superior flatness of cementitious self-leveling compounds (SLCs), four functional additives—water reducers, retarders, defoamers, and water retainers—play pivotal roles. Botai Chemical Building Materials Co., Ltd., leveraging its expertise in construction chemical additives, provides core solutions to address the inherent challenges of balancing high fluidity with strength development and rapid placement with complete hydration.
01 Water Reducers: Foundation of High Fluidity
As the “power engine” of SLC slurries, Botai Chemical’s high-performance polycarboxylate ether (PCE) superplasticizers utilize advanced molecular design to disperse cement particles effectively. They significantly reduce water demand while imparting exceptional flowability and self-leveling characteristics, enabling rapid, uniform spreading and precise floor leveling while enhancing ultimate strength.
02 Retarders: Precision Control of Working Time
Addressing the rapid setting of cements (especially sulphoaluminate/aluminate systems), Botai Chemical’s GYPSUM RETARDER critically regulate hydration kinetics. They extend the operational window for mixing, transportation, placement, and surface finishing. Botai’s retardation solutions ensure consistent performance in large-scale or complex environments, preventing quality defects caused by premature setting.
03 Defoamers: Guardians of Surface Finish and Density
Entrained air during mixing and flow can cause surface defects (pinholes, blemishes) and internal voids, compromising strength and flatness. Botai Chemical’s high-efficiency Defoamers rapidly rupture and eliminate air bubbles. When combined with spiked roller application during installation, they ensure superior surface quality, internal compactness, and mechanical integrity of the hardened SLC layer.
04 Water Retainers: Ensuring Hydration Stability and Bleed Resistance
Botai Chemical’s Vamcell® HPMC/Bomcell® HEMC are vital for SLC system stability. Their exceptional water retention capacity prevents rapid moisture loss to the substrate or evaporation, ensuring complete cement hydration and strength development. Simultaneously, they mitigate bleeding and segregation, maintaining consistent fluidity and homogeneity essential for perfect leveling.
05 The Botai Solution: Synergistic Innovation for Industry Advancement
Water reducers, retarders, defoamers, and water retainers function not in isolation but through precise coordination. Botai Chemical leverages its deep understanding of additive mechanisms and comprehensive product portfolio to provide optimized compounding solutions, achieving synergistic “1+1>2” effects:
Water Reducer-Retarder Synergy: Maintains high fluidity while precisely controlling open time.
Defoamer-Water Retainer Synergy: Ensures surface integrity and density without compromising system stability.
Holistic Performance Enhancement: Collectively contributes to high strength, low shrinkage, superior bond strength, and long-term durability.
Botai Chemical continuously invests in R&D, aligning with industry trends to develop higher-performing, more adaptable (e.g., to varying temperature/humidity), and environmentally progressive additives, driving continuous innovation in cementitious self-leveling technology.
