PC-3016N High Performance Dispersant for Refractories

High Water Reduction and Improved Flowability

PC-3016N is designed to efficiently disperse ultrafine particles in refractory castable systems, allowing the required workability to be achieved with significantly less mixing water. Under suitable formulations, the water demand can typically be reduced by 30–50%, resulting in improved rheology without sacrificing placement performance.

Lower water addition improves particle packing efficiency and minimizes free water trapped between fine particles. This produces castables with higher green density, lower apparent porosity, and a more uniform microstructure after curing. In low-cement and ultra-low-cement refractory systems, reducing water demand is one of the most effective approaches to improving both mechanical properties and high-temperature performance

Excellent Flow Retention

The polymer maintains stable particle dispersion throughout mixing, pumping, and placement. Good flow retention minimizes workability loss during installation and supports self-flowing and self-compacting refractory castables.

Higher Density and Mechanical Strength

Lower water content leads to tighter particle packing and reduced apparent porosity. As a result, refractory castables achieve higher bulk density, improved mechanical strength, better thermal shock resistance, and reduced drying shrinkage.

Low Dosage and Cost Efficiency

Recommended dosage is only 0.05–0.30% of the total dry material. The low addition rate helps reduce production costs while minimizing the introduction of unnecessary components into the refractory system.

Excellent Compatibility

PC-3016N exhibits excellent compatibility with a wide range of refractory binder systems, including low-cement, ultra-low-cement, and cement-free castables. It performs effectively in formulations based on calcium aluminate cement, reactive alumina, silica fume, and other commonly used refractory fine powders.

The product is suitable for various refractory compositions, including alumina, alumina-magnesia, corundum, corundum-spinel, and alumina-silicon carbide systems. As refractory formulations vary considerably, laboratory evaluation is recommended to optimize dosage and verify compatibility with specific raw materials and processing conditions.

Low Cement Refractory Castables

Low-cement castables require efficient particle dispersion to achieve high flowability at low water addition. PC-3016N improves the dispersion of ultrafine powders and calcium aluminate cement, helping reduce water demand while maintaining excellent workability. The resulting dense microstructure contributes to higher mechanical strength, improved abrasion resistance, and better thermal shock performance.

Ultra-Low Cement Castables

Ultra-low-cement castables rely on optimized particle packing and highly efficient dispersants to maintain self-flow characteristics with minimal binder content. PC-3016N supports stable rheology and excellent self-flow performance, enabling the production of dense refractory linings with reduced porosity and improved high-temperature stability.

White Corundum Castables

Corundum-based castables are widely used in severe wear and high-temperature environments where density and slag resistance are critical. PC-3016N promotes uniform dispersion of fine alumina particles, improving particle packing efficiency, installation performance, and the overall structural integrity of high-purity refractory systems.

High Alumina Castables

High-alumina castables are commonly used in steel, cement, and non-ferrous industries where excellent refractoriness and mechanical performance are required. PC-3016N enhances workability while reducing mixing water, helping produce castables with lower porosity, higher bulk density, and improved resistance to thermal cycling.

Electric Furnace and Ladle Linings

Electric furnace linings, ladles, and other high-temperature vessels require refractory materials capable of withstanding severe thermal shock, slag attack, and mechanical wear. PC-3016N improves castable placement while contributing to a dense refractory structure that supports long-term lining reliability in demanding service environments.

Refractory Bricks and Precast Refractory Components

PC-3016N is suitable for refractory bricks, precast blocks, porous plugs, burner blocks, and other shaped refractory components. Stable particle dispersion improves molding performance, increases green density, and helps produce refractory products with consistent dimensional accuracy and mechanical properties after curing and firing

What is PC-3016N used for?

PC-3016N is a high-performance refractory dispersant used to improve the flowability, density, and strength of refractory castables and refractory bricks while reducing mixing water.

Is PC-3016N suitable for low-cement castables?

Yes. It is designed for low-cement, ultra-low-cement, and cement-free refractory systems, providing excellent dispersion and water reduction.

How much PC-3016N should be added?

The recommended dosage is 0.05–0.30% of the total dry materials. The optimum dosage should be determined through laboratory or production trials according to the refractory formulation.

Does PC-3016N improve refractory strength?

Yes. By reducing water demand and improving particle packing, PC-3016N helps increase bulk density, reduce porosity, and improve mechanical strength after curing.

Can PC-3016N be used in self-flow castables?

Yes. Its excellent dispersion performance makes it suitable for self-flowing refractory castables that require high workability without excessive water addition.

Is laboratory testing recommended before production?

Yes. Because refractory raw materials and formulations vary, laboratory and plant trials are recommended to optimize dosage and verify compatibility.

PC-3016N is supplied in 25 kg paper-plastic composite bags. The product has a shelf life of 12 months when stored in a dry, well-ventilated environment. After opening, the package should be tightly sealed to prevent moisture absorption and maintain product performance.

The recommended dosage is 0.05–0.30% of the total dry refractory materials.

Actual dosage should be optimized through laboratory testing according to factors including:

• Refractory formulation
• Cement content
• Fine powder composition
• Required flowability
• Construction method
• Target mechanical performance

For best results, PC-3016N should be blended uniformly with dry materials or dissolved in mixing water before batching. Trial mixing is recommended before large-scale production.
