What Makes Our Dispersant Stand Out?
Your production demands consistent performance, not batch-to-batch variation. Our Dispersant Sodium Naphthalene Sulfonate delivers superior dispersion stability across challenging conditions.
Cross-Industry Versatility: Unlike single-application dispersants, this product performs across pH ranges from 3 to 11 and temperatures up to 130°C. Whether you're formulating agrochemical suspensions or high-strength concrete, you get the same reliable performance.
Zero Contamination Risk: The absence of reducing sugars eliminates fermentation concerns in storage and prevents unwanted reactions with cement systems. Your formulations stay stable longer, reducing waste and customer complaints.
Enhanced Dispersing Efficiency: At equivalent dosages, you'll achieve 2-3 times the dispersing power compared to traditional lignosulfonate products. This means you can reduce dosage rates while maintaining or improving performance—a direct cost saving for your production.
Low-Salt Options for Sensitive Applications: Our specialized low-salt grade (Na₂SO₄ ≤5%) prevents efflorescence on finished surfaces and avoids electrolyte interference in precision formulations where salt content matters.
Core Applications
Agrochemical Definitions: When you're creating Suspension Concentrates (SC) or Water Dispersible Granules (WDG), molecule measure solidness decides item rack life. This dispersant anticipates gem development in difficult water conditions and keeps up uniform dispersion of dynamic fixings. Your details remain homogeneous through capacity and transportation, guaranteeing reliable field performance.
Concrete Admixtures: As a second-generation superplasticizer, it diminishes water request by 15-25% whereas progressing workability. You accomplish higher compressive quality without presenting undesirable discuss entrainment. Execution remains steady indeed in high-temperature casting or muggy situations where other admixtures fail.
Textile and Calfskin Handling: For vat and scatter color applications, fast wetting and leveling activity guarantee uniform color abdicate over texture clumps. It anticipates color movement amid obsession, killing streaking and shade variety that lead to quality rejections.
Pigment and Coating Businesses: In high-solid pounding frameworks, it keeps up moo thickness whereas avoiding reagglomeration. Your processing effectiveness makes strides, and the last item appears way better color quality and sparkle.
Technical Properties You Can Rely On
The anionic structure makes solid electrostatic shock between particles by setting up a strong negative Zeta potential. This overcomes van der Waals fascination powers that cause flocculation.
Heat resistance up to 150°C implies your high-temperature forms won't corrupt its adequacy. The non-foaming characteristic amid high-shear blending avoids discuss capture that compromises item quality.
Chemical compatibility over acidic and antacid frameworks gives you detailing adaptability. It remains steady in multi-component frameworks where other dispersants accelerate or lose activity.
Non-corrosive to metal handling gear and non-toxic to administrators, it fits effortlessly into your existing generation setup without uncommon dealing with requirements.
Quality Control That Protects Your Production
Every clump experiences four basic assessments some time recently shipment. Sodium sulfate substance confirmation anticipates downstream efflorescence issues. Scattering control testing against benchmark measures affirms execution consistency. Fineness estimation (0.63mm strainer) ensures fast disintegration in your blending tanks. pH soundness and calcium particle authoritative capacity tests guarantee viability in difficult water and mineral-rich formulations.
Our in-house research facility performs real-time quality confirmation, and we keep up total traceability documentation for administrative compliance. With EU REACH certification, you can certainly send out wrapped up items to worldwide markets.
Dosage Guidelines
For most powder scattering applications, begin with 2-5% based on dry powder weight. In concrete admixtures, normal dose ranges from 0.5-1.5% of cement weight. The ideal sum depends on your particular strong substance, molecule measure dispersion, and target viscosity.
We prescribe bench-scale testing to decide your perfect measurement. Contact our specialized group at info@cneverstar.com for free test testing back and definition guidance.

FAQ
Q: Why ought to I select low-sulfate grade?
A: Low-sulfate forms (≤5% Na₂SO₄) anticipate white salt ice on wrapped up items and maintain a strategic distance from compatibility issues when combining with other surfactants. If your application is delicate to electrolyte substance or surface appearance things, indicate low-salt grade.
Q: Can it work with cationic surfactants?
A: No. As an anionic surfactant, blending with cationic specialists shapes insoluble complexes that crush scattering. Continuously confirm surfactant compatibility in your formulation.
Q: How does capacity temperature influence performance?
A: The item keeps up steadiness up to 150°C, distant surpassing normal capacity conditions. Keep it in a dry environment to anticipate dampness retention, which can cause caking.
Q: What happens if I overdose?
A: Intemperate dosing (past 5-8%) ordinarily doesn't progress scattering assist and squanders fabric. In concrete applications, extreme overdosing over 2% of cement weight can amplify setting time altogether. Continuously take after prescribed measurement ranges.
Q: Will it alter my product's color?
A: Whereas the powder shows up brown, at commonplace utilization levels (2-5%), it has irrelevant affect on the last color of pigmented frameworks, concrete, or agrochemical concentrates.
Q: How rapidly does it dissolve?
A: With fineness passing 0.63mm sifter and ≥92% strong substance, it breaks down quickly in water beneath direct tumult inside 15-30 minutes at room temperature.
