Sodium Naphthalene Formaldehyde

The Polymol SNF anionic surfactants are a series of sodium salts of alkyl
naphthalene sulfonic acid formaldehyde condensate. These products
provide excellent wetting, dispersing, hydrotroping and medium to low
foaming. They offer acid and base stability, hard-water tolerance and high
temperature stability. The SNF naphthalene sulfonate–formaldehyde
condensates are used primarily as dispersants in a wide variety of
industrial applications. If stored properly in its original sealed packaging
the shelf life is at least 12 months. naphthalene sulfonate condensates. As a powder, it is a convenient
alternative to liquids if your process or storage capabilities are not
suitable. As a low molecular weight dispersant with moderate levels of
sodium sulfate; it is especially useful in dispersions having low solids
content. Because of its economy and versatility, it finds use in many
industrial applications. When heated to decomposition it emits toxic fumes
of oxide of sulpher and carbon.
Polymol SNF is readily soluble in water, glycerol, ethylene glycol and
diethylene glycol and slightly soluble in most alcohols, but insoluble in
most organic solvents. Solubility is not appreciably affected by salts and
acids. Used as a major ingredient in different types of Superplasticizer
formulations. In concrete, it enhances the flow properties of the mix by
dispersing the cement particles and breaking up agglomerates, improving
workability of the mix. and acids.
