摘要： A composition and a process for bonding lignocellulosic material under heat and pressure is disclosed. According to the process, a curing agent is combined with a binder which is an alkaline phenol-formaldehyde resin. In one aspect the combination is by injection into a line carrying the binder to application apparatus, followed by in-line mixing of the curing agent and binder and application of the mixture to the lignocellulosic material. The lignocellulosic material is then compressed and the binder cured. The curing agent may be an ester, a lactone or an organic carbonate. The effect of the curing agent may be moderated with an aliphatic mono or polyhydric alcohol.
