Tamol DN is an anionic dispersant and surfactant commonly used in industrial applications, such as in the formulation of pesticides, dyes, and coatings.
Tamol DN is a water-soluble chemical powder primarily used as a high-performance dispersing agent.
Also known by the chemical designation naphthalenesulfonic acid-formaldehyde condensation product (or DN dispersant), Tamol DN works by ensuring solid particles are evenly suspended in liquid formulations, preventing them from clumping together.

Tamol DN, with the CAS number 9084-06-4, is a non-ionic surfactant commonly used in various industrial applications, particularly in the formulation of paints, coatings, and inks.
Tamol DN is characterized by its ability to improve the dispersion of pigments and fillers in aqueous and non-aqueous systems, enhancing the stability and uniformity of the final product.
Tamol DN exhibits low toxicity and is generally considered safe for use in many applications.
Tamol DN's molecular structure typically includes hydrophilic and hydrophobic segments, allowing it to effectively reduce surface tension and promote wetting.
Tamol DN is also known for its compatibility with a wide range of other additives, making it versatile in formulation chemistry.
Additionally, Tamol DN can function effectively across a range of pH levels and temperatures, contributing to its utility in diverse formulations.
Overall, Tamol DN plays a crucial role in improving the performance and quality of products in which it is incorporated.
Tamol DN series are condensation products of naphthalenesulfonic acid with formaldehyde, they are not surface-active, with the result that they have low wetting power and very little foaming effect.
Tamol DNliquid acts as a a sodium salt of naphthalenesulphonic acid condensation product and as an anionic dispersing agent for agrochemical formulations.
Tamol DN series have an excellent dispersing action and perform well as protective colloids.
They are very versatile stabilizers for aqueous dispersions and emulsions, and for aqueous solutions of surfactants and other auxiliaries.
The various products of Tamol DN series differ from each other in terms of their degree of polycondensation, degree of neutralization, neutralizing agent and salt content.
Furthermore they can be employed as grinding aids and dispersing agents for pigments and dyes in aqueous media, and as precipitants for basic dyes and cationic compounds.
They may also be used as auxiliaries in metal finishing.

Tamol DN is a brown powde，soluble in water, resistant to acid, alkali and hard water.
And Tamol DN has good diffusivity and excelllent resistant to high temperatures than NNO.
Tamol DN is commonly used as dispersant and filler of scattered dyes, reactive dyes, pesticides, leather tanning agent, also water reducing agent for construction and oil well.
Uses
Used as a diluent for pulp control in the paper industry, reducing duplexity, improving filler or fines retention, improving sizing, and reducing coating viscosity.
Used as a high-efficiency dispersant for water-based coatings and pigment pastes.
Used as an adhesive, improve water resistance of filler powder andsealing layers.
Synthesis
The solution of naphthalene(550kg)was heated at 50°C for 4h in the reaction kettle.
Then cool down and pass water vapor to hydrolyze the by-product to give 1-naphthalenesulfonic acid.
After the hydrolysis is completed, formaldehyde (37%) is added under 196kPa.
Finally, alkali is added to neutralize to pH 8-10.
The mixtrue was cooling and crystallization,and filtered out to give the product, Sodium poly[(naphthaleneformaldehyde)sulfonate] .
