Q1: What is the primary function of Sokalan CP 10 in formulations?
A: Sokalan CP 10 is a polyacrylate-based polyelectrolyte surfactant designed primarily to provide dispersion stabilization, viscosity modification, and colloidal stabilization in aqueous systems—especially in pigment dispersions, coatings, and cleaning formulations.
Q2: Is Sokalan CP 10 compatible with common anionic and nonionic surfactants?
A: Yes, Sokalan CP 10 exhibits good compatibility with many anionic and nonionic surfactants, as well as with common water-soluble polymers and co-dispersants. Compatibility should be verified experimentally in the final formulation due to sensitivity to ionic strength and pH.
Q3: How does pH affect the performance of Sokalan CP 10?
A: Sokalan CP 10 is most effective in neutral to slightly alkaline conditions (pH ~7–9), where its carboxylate groups are fully ionized, maximizing electrostatic repulsion and dispersing power. Performance may diminish significantly below pH 5 due to protonation and reduced solubility.
Q4: What is the typical dosage range for Sokalan CP 10 in pigment dispersion applications?
A: Dosage is formulation-dependent, but Sokalan CP 10 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to pigment solids—to achieve effective stabilization without over-thickening or compromising rheology.
Q5: Can Sokalan CP 10 be used in low-VOC or high-solids coating systems?
A: Yes, Sokalan CP 10 is well-suited for low-VOC and high-solids aqueous systems due to its water solubility, minimal foaming tendency, and ability to stabilize particles without requiring high levels of organic co-solvents.
