Finger jointing green southern yellow pine with a soy-based adhesive

Abstract

The authors present results of laboratory tests for a soy-based adhesive to bond southern yellow pine using the finger-jointing method. There was some reason to suspect that finger jointing of southern yellow pine (SYP) with the honeymoon system using soy-based adhesive might prove more difficult than for western species. The Wood Handbook classes western species in the "bond easily" or "bond well" category, whereas SYP is ranked in the "bond satisfactorily" category. On the other hand, the specific gravity and the green moisture content of SYP are nearly identical to those of Douglas fir, a western species that has shown good results with green finger jointing in both laboratory and mill trials. Laboratory and mill trial results soon indicated that results of the honeymoon system with SYP were just as favorable as with western species.
