Pigment Dispersants & Wetting Agents for Coatings

Pigment agglomerates must be wetted, separated, and kept suspended to develop full tinting strength, opacity, and color stability without flocculation
Why It Matters
Pigment agglomerates must be wetted, separated, and kept suspended to develop full tinting strength, opacity, and color stability without flocculation
Solution Approach

Pigment agglomerates must be wetted, separated, and kept suspended to develop full tinting strength, opacity, and color stability without flocculation RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow
1
System & Substrate Assessment
Define the binder system (waterborne, solventborne, UV, powder), substrate, cure, and the VOC, durability, and appearance targets.
2
Additive & Resin Selection
Match resins, pigments and fillers, dispersants, rheology modifiers, defoamers, or biocides to the formulation and compatibility window.
3
Lab Let-Down & Optimization
Dial in loading and addition order through lab let-downs, checking dispersion, rheology, film properties, and storage stability.
4
Application & Performance Testing
Validate on the real application method and substrate, tracking gloss, adhesion, sag, cure, and weathering before scale-up.
Recommended Chemistries (4)
Sodium Polyacrylate
CAS 9003-04-7
Polymers & Resins
Conditioning
Low-MW polyacrylate adsorbs on pigment surfaces and imparts anionic charge, giving electrostatic repulsion that keeps the grind deflocculated

Triethanolamine
CAS 102-71-6
Specialty Additives
Amine neutralizer and co-dispersant
Neutralizes acidic pigment/binder sites and acts as a co-dispersant, improving pigment wetting and color acceptance
Melting Point: 22 °C   Boiling Point: 335 °C at 760 mmHg (Decomposes)   Density: 1.13 at 20 °C
Full Details
Ethoxylated Cocoamine (latex Stabilizer)
CAS 61791-14-8
Surfactants
Surfactancy
Nonionic surfactant that wets hydrophobic pigment surfaces and stabilizes the dispersion in the latex phase
Full Details
Sodium Xylene Sulfonate 40%
CAS 1300-72-7
Surfactants
Cleaning / Degreasing
Hydrotrope/wetting aid that lowers surface tension to speed pigment-water contact during the grind
Melting Point: 27 °C   Boiling Point: 157 °C at 760 mmHg   Density: 1.23
