Q1: What is the primary function of Sokalan PA 70 PN in formulations?
A: Sokalan PA 70 PN is a polyacrylate-based polyelectrolyte surfactant designed primarily for colloidal stabilization and rheology modification. It functions as a dispersant and viscosity controller in aqueous systems, helping to prevent particle agglomeration and maintain uniform suspension of pigments or fillers.
Q2: In which types of industrial applications is this surfactant most commonly used?
A: Sokalan PA 70 PN is widely applied in water-based coatings, construction mortars, ceramic tile adhesives, and pigment dispersions. Its performance is especially valued in high-solids, low-VOC systems where stability under shear and long-term storage are critical.
Q3: How does Sokalan PA 70 PN differ from conventional non-ionic or anionic surfactants?
A: Unlike small-molecule surfactants, Sokalan PA 70 PN is a high-molecular-weight polyelectrolyte that provides steric–electrostatic stabilization. This dual mechanism offers superior resistance to electrolytes and pH fluctuations, and reduces sensitivity to temperature changes during processing and storage.
Q4: What is the typical dosage range for effective performance?
A: Dosage depends on formulation requirements, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the total solids content. Optimal levels should be determined through application-specific testing to balance dispersion efficiency, viscosity, and cost-effectiveness.
Q5: Is Sokalan PA 70 PN compatible with other common additives such as defoamers or biocides?
A: Yes, Sokalan PA 70 PN demonstrates broad compatibility with many standard formulation additives—including silicone and mineral oil-based defoamers, common biocides, and co-dispersants—when added in recommended sequence and concentration. However, compatibility should always be verified in the final system due to potential interactions in complex matrices.
