Dispersant NNO for dye, pigment, agrochemical, rubber and other formulation systems belongs to GreenAgrochem.net, the Green Agrochem Surface & Interface Technology Division. NNO, MF and concrete-grade SNF are related trade-name families in some markets, but they must not be treated as a hierarchy or as automatically interchangeable products.
Use the current Dispersant NNO product and qualification page for identity, application boundaries, grade selection, documentation, trial design and quotation requirements.
Identity and Comparison Corrections
| Former statement | Status | Correct treatment |
|---|---|---|
| NNO is a premium/high-efficiency subtype of SNF with a stronger, more highly polymerized structure. | Unsupported trade-name hierarchy and structural comparison. | Confirm each supplier’s full chemical identity, composition, molecular distribution, grade and intended test methods. |
| NNO is superior and more expensive; general SNF is cheaper and less efficient. | Unsupported technical and commercial generalization. | Compare exact grades using matched specifications, application tests and current dated quotations. |
| NNO is a top concrete superplasticizer. | Formulation-grade NNO cannot inherit concrete-grade SNF claims from its name. | Concrete use requires a documented concrete-admixture grade and concrete-specific qualification. |
Former Grade and Commercial Data Status
| Former value | Evidence/status | Required treatment |
|---|---|---|
| Sodium sulfate ≤5%; general SNF 10–18%. | Possible grade ranges, but no product code, current TDS, test method or source was cited. | Do not use as current specifications or proof of superiority. Match limits to exact grades and governing documents. |
| Solids ≥91%; pH 7–9 at 1%; dispersing force ≥100%. | Unverified grade data without method, reference standard, revision or product code. | Restore only from the current exact-grade TDS/COA with units, basis and methods. |
| 25 kg lined woven/kraft bags and approximately two-year storage. | Generic packaging/shelf-life data without a current specification. | Confirm current packaging and dated shelf-life statement for the offered grade. |
| Approximately USD 2–5/kg. | Stale, unsourced price range without grade, quantity, date, currency basis, Incoterm or destination. | Not a current quotation. Use a dated exact-grade RFQ and landed-cost comparison. |
Former Application Data Status
| Former value | Evidence/status | Required treatment |
|---|---|---|
| Polyester dyeing at 130°C+; NNO 0.5–1.5 g/L; suspension pad dyeing 3–5 g/L; azoic dyeing 0.5–5 g/L. | No exact grade, dye/fibre, liquor ratio, source/revision or complete process. | Not current recommendations. Establish exact-grade starting trials with defined basis and validated temperature profile. |
| Concrete dosage 0.5–1% of cement and water reduction 15–25%. | Unverified application range/result with no concrete system, grade, as-supplied/dry basis, control or method. | Do not present as NNO specification or guarantee; use concrete-grade documents and controlled mix trials. |
Former Safety and Performance Claims
Universal water/acid/alkali/salt/heat stability, non-foaming behavior, non-toxicity, non-flammability, non-explosiveness, perfect colour, fastness, stronger concrete and automatic defect prevention were not supported for an exact grade and system. Use the current SDS and measure the claimed function in the complete formulation.
