SNF-A, SNF-A (3%–5%), SNF-C (18%), Naphthalene-based High-range Water Reducer, SNF Formaldehyde Condensate, Concrete Admixture, Industrial-grade SNF Supplier
Naphthalene sulfonate formaldehyde condensate (SNF/PNS/FDN) is a key raw material for high-range water reducers widely used in construction materials, industrial additives, and concrete engineering. Product purity, sodium sulfate content, and stability directly determine the quality of the engineering project and the performance of the finished product. As a primary supplier with years of experience in the chemical additives industry, Aojin Chemical specializes in the R&D and production of two mainstream SNF specifications: SNF-A (3%–5%) and SNF-C (18%).
I. Core Product Specifications Precisely Aligned with Industry Standards, Suitable for Diverse Operating Conditions
Aojin Chemical precisely controls the core indicators of these two mainstream SNF products. Differentiated formulations meet the needs of various industries and construction scenarios. The products (CAS No.: 36290-04-7; HS Code: 38244010) are fully compliant and safe for use.
1. SNF-A (Sodium Sulfate Content: 3%–5%) – High-Purity Premium Grade
SNF-A is a high-purity naphthalene-based high-range water reducer with low impurity levels. The sodium sulfate content is strictly controlled within the 3%–5% range. It appears as a uniform brownish-yellow powder with a solid content of ≥93%, a chloride ion content below 0.3%, and a stable pH value of 7–9; the water reduction rate reaches 22%–25%. With extremely low impurity levels and excellent dispersibility and fluidity, this grade is ideal for applications requiring strict raw material purity and product stability, effectively preventing issues such as concrete cracking, insufficient strength, or additive failure caused by excessive impurities.
2. SNF-C (Sodium Sulfate Content: 18%) – Cost-Effective General-Purpose Grade
SNF-C is a general-purpose industrial naphthalene-based water reducer with a stable sodium sulfate content of 18%. Featuring a scientifically optimized formulation and outstanding cost-performance, it retains the excellent water-reducing, dispersing, and strength-enhancing properties of the SNF series while significantly lowering procurement costs. The product is highly versatile, suitable for standard applications such as conventional concrete pouring, precast component manufacturing, and mortar preparation. It dissolves rapidly, is compatible with various water qualities and cement types, and offers ease of use with consistent results.
II. Core Advantages of Aojin Chemical’s SNF Series
As a specialized primary supplier of SNF-A and SNF-C, Aojin Chemical leverages mature production processes, a comprehensive quality control system, and large-scale production capacity to create differentiated product advantages. We comprehensively meet diverse needs, including bulk corporate procurement, essential engineering requirements, and export demands.
1. Precise and Stable Parameters; Zero Batch-to-Batch Variation
We strictly control the core parameters for SNF-A (3%–5%) and SNF-C (18%). Every batch undergoes rigorous sampling and testing; key indicators—such as sodium sulfate content, solid content, and water reduction rate—show no significant fluctuations. This eliminates issues regarding color inconsistency or performance deviations between batches, ensuring stability in both construction and production.
2. Excellent Performance; Suitable for Diverse Applications
Both products offer superior dispersing, water-reducing, and slump-retention capabilities. They significantly reduce the water required for concrete mixing, enhance both early-stage and long-term compressive strength, shorten setting times, and improve construction efficiency. Additionally, the products are compatible with a wide pH range (4–9) and exhibit strong weather resistance, maintaining stable performance in both high and low-temperature environments. They are ideal for applications such as civil construction, municipal engineering, bridges and tunnels, precast building materials, and industrial mortars. III. Application Areas: Meeting Essential Industry Needs
Thanks to their stable performance, Aojin Chemical’s SNF-A (3%–5%) and SNF-C (18%) naphthalene-based superplasticizers are utilized across key sectors:
- Construction Engineering: Large-scale infrastructure projects—including commercial concrete, cast-in-place concrete, bridges, roads, tunnels, and water conservancy works—where they enhance concrete strength and durability;
- Prefabricated Building Materials: Production of precast floor slabs, wall panels, cement products, dry-mix mortars, and thermal insulation mortars, optimizing the molding and finish of the final products;
- Industrial Additives: Serving as anionic surfactants in applications such as chemical dispersants, dye auxiliaries, ceramic slurry dispersion, and water treatment additives;
- International Trade & Export: Featuring standardized packaging and compliant specifications, these products are exported globally and serve as a mainstay in the chemical building materials export market.
