Q1: What is the primary function of Sokalan K30 in industrial formulations?
A: Sokalan K30 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 coatings, inks, and construction chemicals.
Q2: Is Sokalan K30 suitable for use in low-VOC or waterborne formulations?
A: Yes, Sokalan K30 is compatible with low-VOC and waterborne systems due to its anionic polymeric structure and absence of volatile organic solvents or alkylphenol ethoxylates, supporting sustainable formulation goals.
Q3: How does Sokalan K30 compare to traditional small-molecule surfactants in terms of stability performance?
A: Unlike conventional low-molecular-weight surfactants, Sokalan K30 provides steric and electrostatic stabilization simultaneously, offering superior long-term dispersion stability, reduced sensitivity to electrolytes, and improved resistance to shear-induced flocculation.
Q4: What is the typical dosage range for Sokalan K30 in pigment dispersions?
A: Dosage is formulation-dependent but generally ranges from 0.1% to 2% by weight relative to pigment solids, with optimal levels determined through application-specific testing to balance stabilization efficiency and rheological behavior.
