Summary

Bark of Khaya ivorensis and Avicennia alba was found to contain 27% and 24%, respectively, of extractable tannins. The performance of adhesives from the tannins showed that the latter could replace phenol in synthetic adhesives. Further improvement was attained by incorporation of formaldehyde. The adhesives are best applied at 25 °C for 5 mins.
