higher t 12 concentrations and mixed with isoset 1000 at a 4 1 weight ratio the mixed adhesives were applied to black spruce pine finger joints 2 u2033 u00d7 4 u2033 cured at ambient temperature and tension tested at different times following application and cure the results recorded are set forth in table 9 similarly pup2 containing 0 6 of t 12 was mixed with vinac xx 210 at 80 20 volume ratio and applied to black spruce pine finger joints 2 u2033 u00d7 4 u2033 the ambient temperature cured strength development tension test are shown below these results demonstrate that when pup2 contained greater than about 0 4 t 12 the finger joints exhibited strengths of greater than 2 880 psi after 45 minutes which is the strength required for the proof load in a typical finger joint commercial line of manufacture in order to adjudge whether the inventive adhesives can qualify for structural property engineered wood applications pup2 of example 2 was mixed with aep from example 3 at 90 10 and 80 20 mix ratios and applied to different wood species for astm d 5751 testing the following results were recorded the above tabulated astm d 5751 test results indicate that the inventive adhesive system is suitable for structural applications such test results include inter alia.
