Rodys O is the aqueous solution of sodium salt of naphthalenesulfonic acid polycondensates with formaldehyde, offered as a 40% aqueous solution. The technology of Rodys O production allows to obtain a product containing trace amounts of free formaldehyde and naphthalene. As a result, it neither has an environmental classification, nor does it affect the content of free aromatic hydrocarbons in the products for which it is used. Among the Rodys product series, Rodys O has a high degree of polymerization.
Rodys O is a polymeric dispersant compound, composed of a hydrophobic main chain, and hydrophilic sulfone groups attached to it. This structure enables both polymer adsorption on the surface of particles, and formation of a layer of unipolar electric charges. Unipolar charges repel each other, causing the breakdown of agglomerates. This makes it possible to produce dispersed systems and non-coagulating suspensions of solids in a continuous liquid phase (water). Rodys O enables the formation of a time-stable dispersion which particles do not re-aggregate for a very long time. Dispersion stability is also expressed by the dynamic viscosity of the system that is constant over time. Rodys O has properties that allow the formation of stable over time dispersions with viscosities enabling their pumpability and the right size of dispersed particles.
Rodys O is mainly dedicated for creating dispersions in water systems. High quality as well as a unique composition means that Rodys O has been used in a wide range of applications (e.g. in agricultural chemistry).
Due to the complexity of the process of creating dispersions, and the variety of characteristic parameters, it is recommended to test the product in conditions as close as possible to those prevailing in the given application.
