What is Sodium Naphthalene Formaldehyde?
Sodium Naphthalene Formaldehyde (SNF) is one of the most widely used and cost-effective high-range water-reducing superplasticizers in the global concrete industry. It is supplied as a brown to dark brown powder or liquid concentrate, working through a dispersing mechanism similar to SMF to reduce the water content needed for workable concrete, while improving compressive strength, durability, and overall concrete quality.
Polychem Industries supplies Sodium Naphthalene Formaldehyde to ready-mix concrete companies, precast concrete manufacturers, and construction chemical formulators across India and internationally. As one of the most economical and widely available superplasticizer chemistries globally, SNF remains a workhorse admixture across general construction applications where its characteristic darker colour is not a limiting factor.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Construction Grade (Powder) | Brown to dark brown free-flowing powder | 90%+ solid content (powder) / 38-42% solids (liquid) | Construction / Concrete Admixture | Ready-mix concrete, precast concrete, mortar, plaster |
| Construction Grade (Liquid) | Dark brown liquid concentrate | 38-42% solids | Construction / Concrete Admixture | Ready-mix concrete, plasticised mortar |
Applications & Uses
Ready-Mix Concrete
The most significant and widespread application. SNF is extensively used in ready-mix concrete production to achieve significant water reduction and improved workability, contributing to higher strength, improved durability, and easier placement and finishing of the concrete.
Precast Concrete Manufacturing
Widely used in precast concrete element production, where its water-reducing performance supports rapid strength development and efficient mould cycle times in industrial precast manufacturing operations.
Mortar & Plaster Applications
Used in mortar and plaster formulations to improve workability and flow characteristics while reducing water content, contributing to improved bond strength and reduced shrinkage cracking in finished plaster and masonry work.
Bridge & Infrastructure Construction
Used in concrete for bridges, dams, and major infrastructure projects requiring durable, high-strength concrete at economical cost, making SNF a popular choice for large-scale infrastructure construction.
General Construction & Housing
Widely used across general residential and commercial construction projects as a cost-effective means of improving concrete workability and quality, supporting efficient construction schedules and consistent concrete performance.
Pumped Concrete Applications
Used in concrete designed for pumping over long distances or to significant heights, where improved flow and reduced water demand support reliable, consistent pumping performance without compromising final concrete quality.
