Rodys L is an aqueous solution of sodium salts of naphthalenesulfonic acid polycondensates with formaldehyde. The production technology of Rodys L allows obtaining a product that neither has an environmental classification, nor does it affect the content of free aromatic hydrocarbons in the products for which it is used. Therefore, Rodys L can be successfully used in various applications.
Rodys L is a polymeric dispersant compound made of a hydrophobic organic chain and hydrophilic sulfone groups. The product has been designed with water dispersions in mind, and among the whole range of Rodys products, Rodys L is a polymer characterized by a high degree of polymerization.
Due to its structure, the dispersant can undergo adsorption on the surface of particles, and form a layer of unipolar electrical charges on them. Unipolar charges repel each other, causing the agglomerates of these particles to break down. It enables the production of both dispersed 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. Dispersion stability is also expressed by the dynamic viscosity of the system that is constant over time. Rodys L exhibits properties that allow the formation of time-stable dispersions with viscosities enabling their pumpability and the right size of dispersed particles.
This product is used in variety demanding applications (e.g. mining industry, wax emulsions), and even as stringent as the textile industry.
Due to the complexity of the process, which is dispersion, and the multitude of key parameters for this process, it is recommended to pre-test the product in conditions as close as possible to those prevailing in the given application
