Minimizing Wood Surface Inactivation At High Temperatures By Boron Compounds

Surface applications of borax and boric-acid-water solutions to freshly peeled coniferous wood veneers are found to be effective for reducing over-drying-induced bonding difficulty of the veneers. The efficiency of this chemical treatment is concentration dependent, being most effective in the low-concentration range (about 0.16 g borax per square foot coverage) and becoming less effective at higher concentrations. The borax solution is considered most suitable for its non metal corrosive nature. Results of some plywood mill runs using phenol-formaldehyde and urea-formaldehyde glues are presented.
