Study of Dryout Resistance of Phenolic Copolymer Resins for Pine Plywood Glues – Part II

This study further explores the relative importance of various alkylated phenol isomers and isomer blends as modifiers in phenolic resins designed to produce broader and longer assembly time tolerance in the manufacture of plywood from southern pine veneer. The glue mixes based on resins where the standard phenol was partially replaced and co-reacted with 3,4-xylenol or with a blend of xylenol-like and trimethyl phenol isomers seemed to offer significantly improved assembly time tolerance. The data also suggest that adequate bond quality might be possible with glue spreads somewhat less than those now in common usage in the manufacture of pine plywood.
