Studies on cashew (anacadium) nut shell liquid and resorcinol modified peanut skin tannin extract for wood adhesives

摘要

Cashew nut shell liquids (CNSL) and resorcinol modified peanut skin extract adhesive resins were prepared. These resins were subsequently used to produce glues for sapele veneer panels. The bond properties of the plywood were evaluated and results show that the glues formulated using resorcinol modified extracts performed better than those modified with cashew nut shell liquid (CNSL). This was attributed to the high reactivity of resorcinol as compared to the cashew nut shell liquid as shown by the gel times of the various resins.
