Features Of Solvay Rhodia Rhodoline WA-40 Wetting Agent

High-efficiency surfactant based on alkylphenol ethoxylate chemistry with optimized HLB for rapid substrate penetration.
Excellent compatibility with anionic, nonionic, and cationic systems in aqueous formulations.
Low foaming profile suitable for high-shear industrial processes including spray coating and roll coating.
Stable performance across broad pH range (pH 4–11) and tolerant to moderate levels of electrolytes.
Reduces surface tension to ≤28 mN/m at 0.1% active concentration in deionized water at 25°C.

Typical Applications Of Solvay Rhodia Rhodoline WA-40 Wetting Agent

Water-based industrial coatings and architectural paints.
Agrochemical formulations, including suspension concentrates (SC) and emulsifiable concentrates (EC).
Textile auxiliaries for dyeing and finishing baths requiring uniform wetting of hydrophobic fibers.
Printing inks—especially flexographic and gravure inks for improved substrate coverage on low-energy surfaces.
Cleaning and metal pretreatment solutions where fast aqueous wetting of oily or oxidized substrates is critical.
