| Notes | Paraformaldehyde reacts with either phenol, urea, melamine or resorcinol to produce resins used as binders in plywood and particleboard. Paraformaldehyde is also used in resin production offers two major advantages as compared with aqueous formaldehyde: (1) more production from existing equipment and (2) less water (typically twenty fold less) to be removed from the reactor product. |
