Two types of adhesives were prepared, one is Resorcinol Adhesive
, and the other is Polyurethane Adhesive.
The cants were then quartered, the exterior surfaces heat treated, resorcinol adhesive
was applied, and the quarters aimed inside-out and clamped together.
Previous studies of the ISO process to produce 4 by 4's (9,16) have used four pieces, required surface heating for a resorcinol adhesive
, and special clamping systems.
The HMR dramatically increased the wet wood failure and resistance to delamination of polyurethanes that were found deficient in the previous study, to levels comparable with the highly durable resorcinol adhesive
The presented database comprises test results on the creep behavior of nine different PU adhesives, five EPI adhesives, and two phenolic resorcinol adhesives
used for reference purposes and not differentiated within the following.
Additional surface preparation is not required for OSB panels when manufacturing glued splice joints using resorcinol adhesives
