Product Description
Construction Amixture/Concrete Water Reducing Agent /Snf/Fdn/Pns Sodium Naphthalene Sulphonate Formaldehyde
Basic information:
1) Chemical name: Sodium Salt of Polynaphthalene Sulfonic Acid
2) CAS number: 36290-04-7
3) Standard: GB 8076-1997
4) Molecular weight: 480.44
Product detail
1. SNF-05 Sodium sulfate content ≤5%
2. SNF-10 Sodium sulfate content ≤10%
3. SNF-18 Sodium sulfate content ≤18%
The lower sodium sulfate content, the better effect of naphthalene sulfonate formaldehyde.
