    摘要: Adhesive composition derived from tannin-furfuryl alcohol catalyzed by acid in a two-part aqueous system is used to bond a variety of wood substrates to give good bond strength and high percentage of wood failure. The reactivity of the mixed adhesive can be controlled by the proper selection of acid catalyst, catalyst concentration, and adhesive composition. This gives adhesive with a wide range of open time during processing. This adhesive system can be either cold set or heat activated. It can also be cured by radio frequency similar to typical industrial settings. These characteristics make this adhesive system suitable for a number of engineered wood applications such as finger joint, Glulam, I-joist, and LVL.
