BASF Tamol NN 7718 Surfactant – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Tamol NN 7718 in industrial formulations?

A: Tamol NN 7718 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 7718 most commonly used?

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

Q3: How does Tamol NN 7718 perform under elevated temperature or high-salt conditions?

A: Tamol NN 7718 exhibits good thermal stability up to typical processing temperatures encountered in industrial mixing and storage, and maintains dispersing efficiency in moderately high-ionic-strength media—making it suitable for formulations containing electrolytes such as calcium or sodium salts.

Q4: Is Tamol NN 7718 compatible with other common additives like defoamers or biocides?

A: Yes, Tamol NN 7718 generally shows broad compatibility with non-ionic surfactants, common defoamers, and preservatives used in industrial aqueous systems. However, compatibility should always be verified experimentally within the specific formulation matrix due to potential interactions with cationic species or highly reactive biocides.

Q5: What is the recommended dosage range for optimal performance?

A: Dosage depends on formulation requirements, but Tamol NN 7718 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to the solid content—to achieve effective dispersion without over-stabilization or foaming issues.
