TAMOL DN is an anionic dispersant based on sodium naphthalene sulfonate formaldehyde condensate.
TAMOL DN is widely used to improve the dispersion and stabilization of inorganic pigments and fillers in aqueous systems.

TAMOL DN provides strong electrostatic repulsion between particles, preventing agglomeration and ensuring uniform distribution, which enhances formulation stability, color development, and processing efficiency.

TAMOL DN is a chemical raw material also known by the synonyms DN dispersant or naphthalenesulfonic acid-formaldehyde condensation product.
TAMOL DN is a water-soluble powder widely used in the chemical industry.

TAMOL DN is primarily used as a dispersant to improve the stability of suspensions and emulsions.
TAMOL DN ensures the uniform distribution of solid particles in liquids and prevents agglomeration.
This reduces the viscosity of the liquid and improves TAMOL DN's processability.

Due to its high dispersibility, TAMOL DN is used in various applications.
TAMOL DN is used in the production of paints and varnishes to distribute pigments evenly and improve color stability.
Furthermore, TAMOL DN is used in the paper and textile industries to disperse fibers and stabilize solid particles.

TAMOL DN has a density of approximately 1.3 g/cm³ and a flash point above 100 °C.
