| Outline of Final Research Achievements |
To develop a new natural adhesive without using fossil resources, adhesive consisting of wattle tannin and sucrose was investigated. The wood-based moldings using wood powder, wattle tannin and sucrose were fabricated under various manufacture conditions. Based on the results obtained, manufacture of particleboard was attempted. The mechanical properties of the board with the best manufacture condition were comparable to JIS standard of 18 type. The curing behavior and basic curing mechanism were also clarified.
