    • 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.
    • 使用两部分水性体系中由酸催化的单宁 - 糠醇得到的粘合剂组合物粘合各种木质基材以提供良好的粘合强度和高百分比的木材破坏。 混合粘合剂的反应性可以通过适当选择酸催化剂,催化剂浓度和粘合剂组成来控制。 这使得在加工期间具有宽范围的开放时间的粘合剂。 该粘合剂系统可以是冷定型或热激活的。 它也可以通过类似于典型工业设置的射频来治愈。 这些特性使得该粘合剂系统适用于许多工程木材应用,例如手指关节,胶合肌,I型托梁和LVL。
