Anionic wetting additive for rapid powder wetting, surface spreading and formulation compatibility.
Sodium Alkyl Naphthalene Sulfonate Wetting Agent supports rapid wetting, spreading and penetration in powder and surface-contact systems.
It improves wetting of hydrophobic or difficult-to-wet powders and helps reduce floating, fish-eye formation and uneven dispersion.
LigninCorp recommends it for industrial pigment, dye, coating, textile and powder-processing applications where fast wetting and medium-to-low foaming performance are needed.
Key Performance Functions
Fast Powder Wetting
Accelerates water penetration into powders and granules.
Surface Spreading
Reduces surface tension and improves solid-liquid contact.
Dispersing Support
Supports the initial wetting stage before full dispersion.
Formulation Compatibility
Compatible with many anionic and nonionic systems after testing.
Industrial Versatility
Useful across dye, pigment, coating and powder-processing systems.
