Sourcing SNF Superplasticizer? ChemicalDekho connects you with major manufacturers like Himadri Chemicals and reputable importers. Access the most cost-effective high-range water reducer for ready-mix concrete.
SNF (CAS 36290-04-7) is the workhorse superplasticizer of the construction industry. By neutralizing surface charges on cement particles, it allows concrete to flow like a liquid with much less water. This increases the final strength and density of the concrete. While PCE is newer, SNF remains the preferred choice for precast elements and standard concrete grades (M20-M40) due to its robustness and lower cost.
Verified listings guarantee low sodium sulfate content (Low Salt) for better compatibility with cements.

Generally considered safe for industrial use. Dust may cause irritation. Not biodegradable.
PCE (3rd gen) gives higher water reduction (30%+) and better slump retention than SNF (2nd gen, 20%). However, SNF is cheaper and less sensitive to clay or silt in the sand.
During manufacturing, Sodium Sulfate is produced as a byproduct. 'Low Salt' (<5%) grades are purified. High salt (>15%) grades can cause crystallization issues (efflorescence) on the concrete surface.
Yes, SNF is often blended with Sodium Lignosulfonate to create a cost-effective admixture that provides both water reduction and retardation.
No, unlike chloride-based accelerators, SNF is non-corrosive to steel reinforcement (rebar).
