Tamol NN 9104 AP is a technical grade anionic dispersant.
Tamol NN 9104 AP is primarily the sodium salt of a condensation product of naphthalenesulfonic acid with formaldehyde.
Tamol NN 9104 AP gives it excellent dispersing and protective colloidal properties.
Tamol NN 9104 AP typically has a low degree of polycondensation.
Key Characteristics: Dispersing Agent: Its primary function is to effectively disperse solid particles (like pigments and fillers) in aqueous media, preventing flocculation and sedimentation.
This leads to more stable and homogeneous formulations.
Tamol NN 9104 AP is typically supplied as a pale to medium brown powder, which is hygroscopic (absorbs moisture).
Tamol NN 9104 anionic surfactant has excellent dispersibility and protective colloidal properties, but has no penetrating foaming surfactants.
Tamol NN 9104 AP has affinity for proteins and polyamide fibers, but not for cotton, hemp, and other fibers.
Stabilizer,dispersing agent and precipitant for the chemical and allied industries;dispersing agent and auxiliary for rubber
production and for processing natural and synthetic rubber latices.
Tamol NN 9104 AP is a solid with a multifunctional role, acting as a sizing agent, plasticizer, dispersant, and anti-caking agent.

Chemical Properties
Sodium poly[(naphthaleneformaldehyde)sulfonate] is a brown powde，soluble in water, resistant to acid, alkali and hard water.
Annd it has good diffusivity and excelllent resistant to high temperatures than NNO.
Sodium poly[(naphthaleneformaldehyde)sulfonate] 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.
Tamoe NN 9104 is the sodium salt of a condensation product of naphthalene-sulfonic acid with formaldehyde.
Tamoθ NN 9104 has a low degree of polycondensation.
The product is identified by the inclusion of a four-digit number in the productname.
The first two digits indicate the typical active content and the last two digitsthe typical sodium sulfate content.
The overall solids content is the sum of the activecontent and salt content.
All the figures are approximate.
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.
Tamol NN 9104 AP is a very versatile stabilizer for aqueous dispersions andemulsions, and for aqueous solutions of surfactants and other auxiliaries.
Tamol NN 9104 AP canalso be employed as grinding aid and dispersing agent for pigments and dyesin aqueous media, and as precipitant for basic dyes and cationic compounds.
Tamol NN 9104 AP may also be used as auxiliary in metal finishing.
Tamol NN 9104 AP has an excellent dispersing action and performs well as protectivecolloid.
Tamol NN 9104 AP is not surface-active, with the result that it has low wetting power andvery little foaming effect.
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] .
