Q1: What is the primary function of Sokalan PA 110 S in industrial formulations?
A: Sokalan PA 110 S is a polyacrylate-based dispersing and stabilizing surfactant designed to prevent particle agglomeration, improve pigment wetting, and enhance colloidal stability—particularly in aqueous systems such as architectural coatings, industrial paints, and pigment concentrates.
Q2: Is Sokalan PA 110 S compatible with other common additives like defoamers or rheology modifiers?
A: Yes, Sokalan PA 110 S generally shows good compatibility with non-ionic surfactants, associative thickeners, and silicone-free defoamers. However, compatibility testing under specific formulation conditions—including pH, ionic strength, and co-additive concentration—is recommended before full-scale implementation.
Q3: How does Sokalan PA 110 S perform in high-pH environments?
A: As a polyelectrolyte, Sokalan PA 110 S exhibits enhanced solubility and dispersion performance at alkaline pH levels (typically above pH 8.0), where its carboxylate groups are fully ionized—making it especially effective in cementitious systems and alkaline architectural coatings.
Q4: Can Sokalan PA 110 S be used in low-VOC or zero-VOC formulations?
A: Yes—Sokalan PA 110 S is supplied as an aqueous solution with negligible VOC content and no added solvents or APEOs, supporting compliance with low-VOC regulatory frameworks and sustainability targets in modern coating and construction chemical applications.
