Available in light brown powder form with ≥92% solid content and pH 7-9, our SNF grades range from premium SNF-A (≤5% Na₂SO₄, 26% max water reduction) to economy SNF-C (≤18% Na₂SO₄), serving both high-strength concrete and industrial dispersant Applications.
What Makes Our Naphthalene Superplasticizer Stand Out?
Three Performance Grades Engineered for Your Needs
We manufacture three distinct grades because lower sodium sulfate content directly translates to higher active SNF concentration and superior concrete performance:
| Grade | Na₂SO₄ Content | Chloride (Cl⁻) | Fluidity | Max Water Reduction | Best For |
|---|---|---|---|---|---|
| SNF-A | ≤5% | ≤0.3% | ≥250mm | 26% | C50+ high-strength concrete, critical infrastructure |
| SNF-B | ≤10% | ≤0.4% | ≥240mm | 25% | General construction, commercial buildings |
| SNF-C | ≤18% | ≤0.5% | ≥230mm | 23% | Cost-effective concrete, industrial dispersant use |

How It Works for You?
When you add this admixture to your concrete mix, it adsorbs onto cement particle surfaces. This creates strong negative charges that generate electrostatic repulsion, breaking up cement flocs and releasing trapped water. The result? You get excellent workability without adding extra water that would compromise strength.
Where You'll Get Maximum Value?
Precast Concrete Production
Speed up your production cycles dramatically. Our Naphthalene Superplasticizer enables rapid early strength development, allowing 12-to-18-hour mold turnover. You'll increase factory throughput while maintaining structural integrity.
High-Strength Construction Projects
For C60-C80 review concrete in high rises and high-rises, you require admixtures that perform beneath weight. Thick fortification situations require high-flow characteristics—our SNF-A review gives self-compacting properties that fill complex formwork without segregation.
Infrastructure and Pressure driven Engineering
Bridges, dams, and marine structures request long-term solidness. By lessening water-cement proportions whereas keeping up workability, you'll make denser microstructures with upgraded resistance to sulfate assault and chloride penetration.
Industrial Applications Past Construction
Our item serves double purposes. Past concrete, it capacities as an viable dispersant in calfskin handling, material fabricating, and color generation businesses.
Practical Dosage Guidelines
Standard Dosage Range: 0.5-1.0% by weight of cementitious materials
For Maximum Water Reduction:
- At 0.75% dosage: expect 18-22% water reduction
- At 1.0% dosage: achieve up to 25-26% reduction (SNF-A grade)
Important Application Notes:
- Add during concrete mixing after partial water addition
- Compatible with retarders, air-entrainers, and supplementary cementitious materials
- Adjust dosage based on cement type, temperature, and required slump retention
When Using Retarders: If combining with set-retarding admixtures at normal dosages (0.03-0.15%), expect 2-7 hours of setting delay under 20-35°C conditions with ordinary Portland cement.
Quality Assurance You Can Verify
We comply with multiple international standards:
- ASTM C494 Type F: High-range water-reducing admixtures
- EN 934-2: European concrete admixture standards

FAQ
Q: How does the item compare to polycarboxylate-based admixtures?
A: Whereas PCE admixtures offer higher water decrease (30-40%), our naphthalene-based item gives great cost-performance adjust for C30-C80 review concrete. It's especially viable when you require dependable execution with unsurprising comes about and superior compatibility with different cement types.
Q: What happens if I inadvertently overdose?
A: Dose accuracy things altogether:
- Slight overdose (up to +0.2%): With proper moist curing, final strength remains essentially normal
- Moderate overdose (+0.2% to +0.3%): Expect 24-72 hour setting delays, reduced early strength, and 5-10% decrease in 28-day strength
- Severe overdose (>+0.3%): Risk of prolonged non-setting and potential element rejection
Continuously degree carefully and conduct trial blends when changing cement sources or blend designs.
Q: Will this item erode my steel reinforcement?
A: No. Our chloride substance remains well underneath basic limits (≤0.3-0.5% depending on review), guaranteeing no hazard of galvanic erosion in strengthened concrete structures.
Q: Can I utilize this in cold climate conditions?
A: Yes, but pay consideration to sodium sulfate substance. Lower Na₂SO₄ grades (SNF-A and SNF-B) stand up to crystallization way better in cold temperatures. For winter development, we suggest our premium grades and appropriate blend plan adjustments.
Q: How ought to I store this product?
A: Store in dry, secured conditions absent from dampness. The powder frame has great rack stability—typically 12 months in unopened bundling. Once opened, reseal firmly and utilize inside 3 months for ideal performance.
Q: Do you give tests for testing with our particular cement?
A: Completely. We offer free tests for compatibility testing and execution confirmation. Since cement characteristics change by locale and provider, we unequivocally suggest conducting trial blends some time recently full-scale generation. Contact our specialized group for test demands and blend plan assistance.
Q: What's your least arrange quantity?
A: We're adaptable. Trial orders begin from fair a few packs, whereas bulk clients advantage from full holder estimating. Our huge stock capacity implies we can fulfill orders of any estimate rapidly.
