Grade-specific buying brief
Confirm SNF identity and the offered sulfate grade
This product is a naphthalene-based superplasticizer, commonly described in the market as sulfonated naphthalene formaldehyde (SNF). It is not raw naphthalene. Use the full admixture identity and grade on the inquiry, quotation and COA so the short page name cannot create a purchasing ambiguity.
For comparison, ask for the offered grade's solids, sulfate, chloride, moisture and pH specification with test methods and reporting basis. The catalogue values above should be checked against the current offer. Compare the finished concrete's workability window and strength requirements with the alternative PCE route, rather than assuming equal product mass gives equal performance. No fixed replacement ratio is established here.
