1. The utilization of two different HTL-bio-oils (W-HTL-bio-oii and WE-HTL-bio-oil) was investigated for the synthesis of epoxy resin. 2. The distribution of OH groups within bio-oi! (aliphatic, phenolic and acidic OH) plays an important role on the yield and EEW of epoxy resin. 3. Curing kinetics and FT-IR analysis revealed that curing of BOBER was mainly controlled by etherification reaction. 4. DMA analysis showed that BOBER-WE had a higher storage modulus (845 MPa), glass transition temperature (96 °C), and crosslink density (58.7 mol/m3) than BOBER-W (425 MPa, 63.6 °C, and 8.5 mol/m3), suggesting that addition of ethanol in HTL process improved the thermomecrsanical properties of epoxy resin. 5. Lab shear test showed that bio-oil based epoxy resins are comparable to the commercial epoxy resin in dry and wet conditions.
