Rodys CP is the powder equivalent of Rodys C. It comes in the form of light brown powder with low moisture content, which makes it a financially advantageous solution in terms of storage or transport.
Both Rodys CP and its liquid equivalent Rodys C, is a high quality product that neither has an environmental classification, nor does it pose a threat to the health and life of living organisms. Its key parameters are under strict control, therefore Rodys CP does not contribute to the increase of the content of free aromatic hydrocarbons in finished products.
Rodys CP is a polymeric dispersant, which is the sodium salt of naphthalene sulfonic acids with formaldehyde, characterized by a moderate degree of polymerization. In its structure, one can distinguish a hydrophobic main chain and hydrophilic side groups – sulfone groups. This structure clearly implies a mechanism of action of the dispersant, which by adsorbing itself on the surface of the particles, forms a coating of unipolar charges. Electrostatic forces, by causing mutual repulsion of charges, lead to the breakdown of agglomerates. Thus, it is possible to create colloidal systems and non-coagulating suspended solids in the continuous liquid phase (water).
Rodys CP enables the formation of a dispersion stable in time, which is manifested in a very low tendency to re-aggregation of particles and constant dynamic viscosity of the system over time. The resulting water dispersions are characterized by the appropriate size of dispersed particles, and viscosities enabling their pumpability.
The product is particularly well suited as a dispersant of agrochemicals, and in the textile and tanning industry. It can be used in various colloidal systems or permanent aqueous suspensions. Due to the complexity of the process, which is the creation of dispersion, and the variety of key parameters for it, it is recommended to test the product in conditions as close as possible to those prevailing in the given application.
