Abstract:
The present invention relates to a process for reducing the content of free formaldehyde in a commercial phenol-formaldehyde resin, comprising the step of treating a phenol-formaldehyde resin with at least one phenol derivative or aniline derivative, wherein the pH of the resin is 7 or higher. The present invention further relates to a phenol-formaldehyde resin resulting from this process. The phenol-formaldehyde resin obtained by the process of the present invention may be used for the preparation of a binder composition for mineral wool products.
