Sodium Naphthalene sulfonate formaldehyde condensate concrete water reducer

Naphthalene based superplasticizer are also known as sodium naphthalene sulfonate formaldehyde, are a class of high-range water reducers widely used in the concrete industry. As a cost-effective concrete admixture, SNF superplasticizer is synthesized from naphthalene, sulfuric acid, and formaldehyde.This product is high concentrated and low-alkali. It has good dispersing performance to cement particles.Compared with traditional plasticizer, it has higher water reducing rate and less corrosion to steel bar which greatly improve the shelf life of concrete buildings. It offers reliable water reduction (15-25%), improves concrete workability, and enhances early/late strength. it suits low-rise buildings, rural construction, and industrial projects where cost-performance is key. Compliant with industry standards, SNF delivers stable performance while reducing cement dosage, making it a trusted choice for global concrete applications.

Key Performance:

1. Low sodium sulfate, high concentrated, and low alkali content can help to avoid the alkali-aggregate reaction, crystalline and precipitation at negative temperature.

1. High water reduction rate, achieves a water reduction rate of up to 28% ( 18-28%), significantly lowering the water-cement ratio and enhancing concrete strength and durability.

2. Improve the workability of concrete and enhance concrete property, such as fracture resistance, compressive resistance and long term strength etc.

3. Superior compatibility. It works well with various cement types (ordinary portland cement, slag cement, fly ash cement and be mother material to formulate other functional admixtures, like type of early strength, set retarding, pumping, and antifreezing etc.

4. Cost-effectiveness. Reduces cement usage by 10-25% while maintaining performance, making it ideal for budget-conscious projects ( low-rise buildings, rural construction).
