Sreemaa Chemicals supplies Sodium Naphthalene Formaldehyde Sulfonate, a polycondensate-based superplasticizer used to reduce water content in concrete without sacrificing workability. This additive lowers the water-cement ratio by 15% to 30%, improving compressive strength and durability in ready-mix and precast applications. The material is delivered as a dark brown liquid or powder, depending on formulation, and is compatible with Portland cement types I through V.
The compound is manufactured to meet ASTM C494 Type F standards for high-range water-reducing admixtures. Typical industry concentrations range from 0.1% to 0.5% by weight of cement, with variations based on ambient temperature and aggregate type. It is stable in storage for up to 12 months under ambient conditions and does not contain chloride ions, making it suitable for reinforced concrete. No synthetic retarders or accelerators are added unless specified by the buyer.
This additive is primarily purchased by concrete batch plants in South Asia, the Middle East, and Southeast Asia for infrastructure projects including bridges, high-rise buildings, and precast panels. Buyers typically order in 200kg drums or 1000kg IBC totes. Standard trade terms are FOB Kolkata or CIF port of destination, with payment via T/T or L/C. Lead time is 7 to 14 days after order confirmation, subject to stock availability.

Before ordering, confirm the exact chemical composition and active content percentage with a certificate of analysis. Request a sample batch to test compatibility with your cement and aggregates. Verify that the product meets ASTM C494 Type F or equivalent standards. Do not rely on supplier claims without independent lab validation, especially for structural applications.
Confirm Incoterms with the supplier - FOB Kolkata is standard, but CIF terms may be negotiable. Lead time is typically 7 to 14 days, but shipping schedules from Indian ports can vary. Payment is usually via T/T advance or L/C at sight. Ensure the bill of lading specifies the correct HS code for chemical admixtures (3824.90) to avoid customs delays.
On delivery, inspect packaging for moisture damage or leakage. Conduct a slump test and compressive strength test on a trial batch. Request a batch-specific test report covering pH, chloride content, and water reduction efficiency. Retain a sample from each shipment for quality dispute purposes. Documentation should include MSDS, COA, and export declaration.
