Formaldehyde → Resorcinol-formaldehyde resin

Participants

Reaction Steps

The present invention also provides a method for preparing such a treating agent, which comprises adding resorcinol and formaldehyde to an aqueous sodium hydroxide solution, followed by aging to obtain a resorcinol/formaldehyde mixture, and mixing to the resorcinol/formaldehyde mixture a latex component obtained by adding a surfactant in an amount corresponding to from 0.8 to 2.5 wt % based on the weight of the RFL, during the polymerization of the polymer component of the latex.
