ABSTRACT:
A pre-cure resistant powder resin binder for waferboard/oriented strandboard manufacture is manufactured from spray drying a liquid resin composition containing a low advanced phenol-formaldehyde resin and a water soluble oxo compound of boron. The spray dryability of the low molecular weight phenol-formaldehyde resin is enhanced by the addition of the oxo boron compound.
