BASF Tamol NN 8906 Surfactant – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Tamol NN 8906 in industrial formulations?

A: Tamol NN 8906 is a sodium naphthalene formaldehyde condensate surfactant designed primarily as a dispersing agent and wetting aid. It helps stabilize pigment and filler particles in aqueous systems by providing electrostatic repulsion and steric hindrance, thereby improving suspension stability, reducing viscosity, and enhancing uniformity in final products.

Q2: In which types of industrial applications is Tamol NN 8906 most commonly used?

A: This surfactant is widely employed in water-based coatings, construction chemicals (e.g., cement admixtures and tile adhesives), agrochemical suspensions (SC and SE formulations), and ceramic slurries—where effective particle dispersion and rheological control in high-ionic-strength environments are critical.

Q3: How does Tamol NN 8906 perform in hard water or high-salt conditions?

A: As a robust anionic dispersant with low sensitivity to multivalent cations, Tamol NN 8906 maintains good performance in moderately hard water and saline media—making it suitable for formulations where electrolyte tolerance is required, such as in concrete additives or certain pesticide concentrates.

Q4: Is Tamol NN 8906 compatible with other common surfactants or rheology modifiers?

A: Yes, Tamol NN 8906 is generally compatible with nonionic surfactants, associative thickeners, and many cellulose ethers. However, direct combination with strongly cationic species may reduce its effectiveness due to potential charge neutralization; compatibility testing under actual formulation conditions is recommended.

Q5: What is the typical dosage range for Tamol NN 8906 in a standard dispersion system?

A: Dosage depends on the nature and loading of dispersed solids, but Tamol NN 8906 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to the solid phase—to achieve effective stabilization without over-dosing or adverse foaming effects.
