Rodys O is the 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.
