to about 80 to 140EC for a time sufficient to advance the
resin to a B-stage; forming a mat or stack of the wood
components coated with the B-stage resin; exposing the mat or

steam atmosphere in a hot press and compressing the layup to
form the consolidated wood product; wherein the B-stageable
phenol-formaldehyde resole resin has a number average
molecular weight of between about 200 and 600, has a F:P mole
ratio of about 1.3:1 to 2.0:1, and has been modified with 0 to
about 5.5 wt % of caustic based on resin solids.
The references set forth below are relied upon by
