Q1: What is the primary function of Sokalan HP 22 in industrial formulations?
A: Sokalan HP 22 is a polyacrylate-based dispersing and stabilizing surfactant designed to prevent particle agglomeration, enhance pigment wetting, and improve colloidal stability—particularly in aqueous systems such as coatings, construction mortars, and ceramic tile adhesives.
Q2: Is Sokalan HP 22 suitable for use in low-VOC or eco-labeled formulations?
A: Yes—Sokalan HP 22 is anionic, non-alkylphenol ethoxylate (APEO)-free, and compatible with many environmentally focused formulation strategies. It supports VOC reduction by enabling stable high-solids dispersions without requiring volatile co-solvents.
Q3: How does Sokalan HP 22 perform under high-salt or alkaline conditions?
A: Sokalan HP 22 exhibits good tolerance to moderate levels of electrolytes and maintains performance across a broad pH range (typically pH 5–12), making it well-suited for cementitious and highly alkaline building material applications.
Q4: Can Sokalan HP 22 be used in combination with other rheology modifiers or surfactants?
A: Yes—it is generally compatible with common cellulose ethers, associative thickeners, and nonionic surfactants. However, compatibility testing is recommended when combining with cationic additives or highly charged polyelectrolytes to avoid potential destabilization.
