Q1: What is the primary function of Sokalan CP 7 in formulations?
A: Sokalan CP 7 is a polyacrylic acid-based dispersant and stabilizer designed to prevent particle agglomeration, improve pigment wetting, and enhance long-term colloidal stability—particularly in aqueous systems such as architectural coatings, industrial paints, and inkjet inks.
Q2: Is Sokalan CP 7 suitable for use in low-VOC or zero-VOC formulations?
A: Yes. As a water-soluble, non-ionic polymer with no added solvents or volatile organic carriers, Sokalan CP 7 supports the development of low-VOC and zero-VOC formulations without compromising dispersion performance or storage stability.
Q3: How does Sokalan CP 7 compare to traditional surfactants in terms of foaming behavior?
A: Unlike many low-molecular-weight surfactants, Sokalan CP 7 exhibits very low foaming tendency due to its polymeric nature and lack of micelle-forming amphiphilic structure—making it especially suitable for high-shear processes and applications where foam control is critical.
Q4: Can Sokalan CP 7 be used in combination with other rheology modifiers or associative thickeners?
A: Yes. Sokalan CP 7 is generally compatible with common cellulose ethers, hydrophobically modified ethoxylated urethanes (HEURs), and acrylic thickeners—though optimal synergy and dosage should be confirmed via formulation-specific compatibility testing under intended processing and storage conditions.
