Blending resins possess the capability of room temperature curing, and had the gel time significantly shorter than that of epoxy resin. Adjusting the pH value of liquefied Japanese cedar could prolong the gel time and increase the weight retention of the cured resin after dissolve testing.

掺合树脂具备常温胶化性，其胶化时间较环氧树脂大幅缩短，调整液化柳杉之pH値可延长其胶化时间，亦可增加其硬化树脂溶出试验之重量保留率。

DSC thermo-analysis showed that both of epoxy resins and blended resins had an exothermic peak during the period of thermal-scanning due to the curing reaction. Comparison between different kinds of liquefied wood, blending resins that using the liquefied Japanese cedar of LW-C as the raw material would undergo more degree of cross-linking reaction. They released more reaction heat, and formed a more complete cross-linking structure. However, heat treatment could promote an advanced cross-linking reaction of room temperature cured resins. DSC isothermosetting analyses showed that the curing reaction of both epoxy resins and blended resins conformed to Arrhenius kinetic model. The time needed to achieve 95% of curing reaction was shorter for blending resin than that of epoxy resin.

由DSC热分析显示环氧树脂与掺合树脂在热扫描过程中均出现硬化反应放热峰，其中以液化柳杉LW-C为原料之掺合树脂在硬化过程可进行较多之架桥反应，其反应放热量较大，硬化树脂之架桥结构较完整，而加热可促进常温硬化树脂进一步之架桥反应；由DSC等温硬化性分析显示环氧树脂与掺合树脂之硬化反应均符合Arrhenius动力学模式，添加液化柳杉之掺合树脂达95%硬化率所需时间较环氧树脂短。
