Abstract
Tannins such as those extracted from bark can be employed to substitute more expensive petrochemical components in adhesives used in wood gluing applications. Recent work has determined the extracts of radiate pine bark can successfully be incorporated into cold set adhesives. FTIR chemical imaging has been used to visualized and characterised both PRF and tannin-based adhesive glue lines probing the wood-adhesive interphase of the adhesive glueline. Comparison between the two adhesives revealed similar spatial distribution of the adhesive with respect to glueline penetration. The similar glue line properties were consistent with adhesive testing results which indicated similar bond strength and wood failure between the adhesives. Chemical imaging also revealed the tannin and PRF components in the tannin-based adhesive do not separate into separate phases when applied to wood.
