Q1: What is the primary function of TAMOL NH 8807 in industrial formulations?
A: TAMOL NH 8807 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 grind efficiency, suspension stability, and rheological behavior.
Q2: In which types of applications is TAMOL NH 8807 most commonly used?
A: It is widely employed in water-based coatings (e.g., architectural and industrial paints), construction chemicals (such as cementitious tile adhesives and grouts), agrochemical suspensions (SC and SE formulations), and ceramic slip systems—where robust particle dispersion and low-viscosity stabilization are required.
Q3: How does TAMOL NH 8807 compare to other naphthalene sulfonate dispersants in terms of performance and compatibility?
A: TAMOL NH 8807 offers enhanced thermal and electrolyte tolerance compared to standard naphthalene formaldehyde condensates, supporting stable dispersions in high-ionic-strength or elevated-temperature environments. Its tailored molecular weight distribution also improves compatibility with a broad range of binders, including acrylics, styrene-butadiene, and polyvinyl acetate emulsions.
Q4: What is the typical dosage range for TAMOL NH 8807 in pigment dispersion applications?
A: Dosage depends on pigment type, loading, and desired stability profile, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to pigment solids. Optimization is recommended via lab-scale dispersion trials under application-relevant conditions.
