| Summary: | Fingerjoints and woodlam GST (Glued Laminated Timber) were prepared with beech wood on
industrial scale with a cold-set honeymoon type adhesive comprising 65% of natural material, namely
condensed flavonoid tannin, already developed to satisfy the relevant adhesives standard requirements. The
adhesive system stood up to the scaling up to industrial dimension with good performance of strength. The
strength characteristic were compared with those obtained with a 50% natural material honeymoon adhesive
already in commercial operation for several decades with yielding even better results. Full scale fingerjoints
and woodlam prepared with beech timber gave good results. The fast-set characteristics of the adhesive
system were maintained in the scaling up too. |
