Sodium Naphthalene Sulfonate Formaldehyde (SNF / PNS)

Composition and Chemical Properties

SNF / PNS is a negative polymer created by joining naphthalene sulfonic acid with formaldehyde. SNF / PNS disperses cement particles, frees water, and improves concrete workability without extra water.

Uses:

• Ready‑Mix Concrete: Improves slump, pumpability, and placing performance.
• Precast Concrete: Helps with strength and a smoother surface finish.
• High‑Strength Concrete: Lowers the ratio for stronger and denser structures.
• Grouts and Repair Mortars: Improve filling ability in cement‑based materials.

Quality Parameters:

• Solid Content: 91 to 92 percent or higher.
• Moisture Content: 8 percent or less.
• PH Value: 7 to 10.
• Water Reduction: 15 to 25 percent.
• Appearance: Uniform brown, free‑flowing powder.
• Chloride Content: Low or chloride‑free for reinforced concrete.

Always ask for a Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS) before ordering.
