Dispersant NNO used for rubber-compounding dispersions or aqueous latex systems belongs to GreenAgrochem.net, the Green Agrochem Surface & Interface Technology Division. NNO may support the distribution of compatible fillers or pigments, but it is not a universal latex stabilizer.

Former Dosage and Product Data Status
| Former value | Evidence/status | Required treatment |
|---|---|---|
| 2–4% of dry additive/filler weight; example 2–4 g NNO per 100 g dry additives. | No exact NNO grade, supplier document/revision, polymer/latex, filler, dry-active basis or method was identified. | Not a current supplier recommendation. Restore only as an exact-grade starting trial range with its basis and validation conditions. |
| Prepare a 10% solution using one part NNO to nine parts water. | Generic preparation guidance without exact-grade solubility, water quality, temperature or handling source. | Use the current TDS/SDS and plant procedure; verify dissolution and solution stability. |
| Three percent of dry additives in the zinc-oxide example. | Illustrative value without an identified formulation, control or result. | Not production guidance or evidence of performance. |
| Approximately two-year storage stability. | No current exact-grade shelf-life document or packaging/storage conditions were cited. | Use only the current supplier shelf-life statement for the offered grade and packaging. |
Former Performance and Safety Claims
| Former claim | Status | Correct approach |
|---|---|---|
| Keeps natural or synthetic latex uniformly stable and prevents coagulation, settling or separation. | Unsupported universal latex-stability claim; an anionic dispersant may destabilize some systems. | Compare coagulum, grit, mechanical/storage stability, foam and film properties with a matched control. |
| Non-foaming and universally stable to heat, acids, alkalis, salts and hard water. | Unverified compatibility and performance claims. | Test exact water, pH, electrolyte, surfactant package, temperature and process; evaluate antifoam separately. |
| Improves final strength, flexibility, durability and defect rate while reducing processing time and cost. | Unverified compound, manufacturing and commercial outcomes. | Measure dispersion, cure, tensile, elongation, abrasion, ageing and cost-in-use under defined conditions. |
| Non-toxic, non-flammable and safe to handle. | Absolute safety wording unsupported without the exact current SDS and site risk assessment. | Follow the grade-specific SDS, dust controls, PPE and local handling requirements. |
