High-Performance Dispersing Agent for Water-Based Paints, Coatings & Pigment Systems

Sodium polyacrylate is a highly efficient anionic polymer dispersant widely used in water-based paints, architectural coatings, industrial coatings, pigment slurries, inks, and various aqueous formulation systems. Thanks to its excellent dispersing power, electrostatic stabilization, and compatibility with a broad range of pigments and fillers, it has become one of the most trusted dispersing additives in modern coating technology.

At GELSAP, we specialize in producing high-purity, industry-grade sodium polyacrylate designed to meet the demanding requirements of today’s paint manufacturers. Whether you produce decorative paints, automotive coatings, waterproof coatings, primers, emulsions, or printing systems, our sodium polyacrylate dispersant provides stable, reliable performance that enhances product quality and reduces overall formulation costs.

What Is Sodium Polyacrylate?

Sodium polyacrylate is a water-soluble polymer derived from acrylic acid. Because of its strong anionic charge density, it effectively prevents pigment and filler particles from re-agglomerating. This ensures uniform particle distribution, stability, and improved color strength in paint systems.

In coating formulations, sodium polyacrylate acts as:

• Dispersant

• Stabilizer

• Viscosity modifier

• Anti-settling agent

• Processing aid

Its versatility, cost-effectiveness, and environmental safety make it a preferred choice in water-based systems.

Key Features & Benefits

1. Superior Pigment Dispersion

Our sodium polyacrylate provides strong adsorption on pigment surfaces, creating a stable electrostatic barrier that prevents agglomeration. This leads to:

• Finer particle size distribution

• Enhanced color development

• Improved opacity and tinting strength

• Better gloss and film uniformity

Even difficult pigments—such as titanium dioxide, carbon black, iron oxide, and organic pigments—are dispersed easily and remain stable.

---

2. Excellent Long-Term Storage Stability

Paints formulated with our sodium polyacrylate resist:

• Sedimentation

• Hard-settling

• Viscosity drift

• Flocculation

Your paint remains stable even under temperature fluctuations or long storage periods, reducing the risk of product returns and customer complaints.

---

3. Reduced Pigment Usage & Lower Production Costs

Because dispersion efficiency is significantly improved, you can achieve the same color strength using less pigment or filler. This optimization helps manufacturers:

• Lower raw material costs

• Improve formulation efficiency

• Increase output stability

• Minimize processing time during grinding and mixing

---

4. Wide Compatibility with Water-Based Systems

Our sodium polyacrylate dispersant works synergistically with:

• Water-based emulsions (acrylic, styrene acrylic, vinyl acetate, polyurethane)

• Pigment concentrates

• Latex paints

• Architectural coatings

• Industrial waterborne coatings

• Waterproofing formulations

• Mining and ceramic slurries

• Inks and pigment pastes

Its performance remains stable across a wide pH and temperature range.

---

5. Improved Rheology & Application Performance

Sodium polyacrylate aids in achieving optimal viscosity control without sacrificing flow behavior. It improves:

• Brushability

• Rollability

• Leveling

• Anti-sagging properties

• Film uniformity

End-users will enjoy smoother, more consistent application results.

---

6. Eco-Friendly & Low-VOC

As a water-soluble polymer, sodium polyacrylate:

• Contains no volatile organic compounds (VOCs)

• Meets environmental compliance standards

• Supports green coating innovation

This makes your product more sustainable and market-friendly.

How to Use Sodium Polyacrylate in Paints

Recommended Use Method

1. Pre-dissolve sodium polyacrylate in water to form a 10–20% solution.

2. Add into the pigment grinding stage for optimal dispersion.

3. Adjust dosage according to pigment load and viscosity requirements.

Typical Dosage

• 0.2%–0.6% for titanium dioxide

• 0.3%–1.0% for carbon black

• 0.1%–0.3% for fillers (CaCO₃, kaolin, talc)

Higher pigment loads may require slightly increased dosage.
