Exterior Glues for Plywood

The author presents a thorough discussion of the development of exterior (phenolic) glues for plywood starting with the use of Tego films in the early 1930’s through the gradual development of the “tailored” phenolic resins of the 1960’s. Specific discussions include: 1) the importance of reducing press time by considering lighter glue spreads with phenolic resins that allow adequate flow, 2) an analysis of the “ideal” exterior plywood glue, in which the author concludes that the best candidate is based on alkali soluble phenolic resins, 3) a review of the development of the southern pine plywood industry with emphasis on the problems of achieving shortest possible press times, 4) the use of prepressing and the importance of tailoring phenolic glues for prepressing operations to insure adequate cold press bonding, and 5) a look at the future of phenolic glues in the plywood industry, especially in relation to their possible use in automated plywood manufacture.
