Rodys L disperser, 1000 kg container

Rodys L is a sodium salt of polycondensate of naphthalenic acids with formaldehyde, offered in liquid form. The production technology of Rodys L allows to obtain a product containing trace amounts of free formaldehyde and free naphthalene. Thanks to this, it does not have an environmental classification and does not affect the content of free aromatic hydrocarbons in the products for which it is used.

Rodys L is a dispersing compound composed of a hydrophobic organic chain and a hydrophilic inorganic sulfone group. Thanks to this, it can adsorb on particles of solids and create a layer of identical electric charges on them (sulfone groups). The like charges repel each other, causing the agglomerates of these particles to disintegrate. This makes it possible to produce mostly colloidal systems and non-coagulating suspensions of solids in a continuous liquid phase (water). Rodys L enables the formation of a time-stable dispersion, which inhibits the re-aggregation of particles. The stability of the dispersion is also expressed by the dynamic viscosity of the system which is constant over time.

Rodys L exhibits properties that allow the formation of time-stable dispersions with viscosities enabling their pumpability and the appropriate size of dispersed particles. It can be used in other types of colloidal systems or stable aqueous suspensions. Due to the complexity of the dispersion formation process and the variety of their characteristic parameters, it is recommended to test the product in laboratory conditions.

Rodys L is a high-quality product and is recommended for creating dispersions in water systems.
