The SC-CTL was impregnated with different kraft BL and BL/PF resin concentrations (i.e., 10, 15, 20 and 25% w/w) using the vacuum pressure method. Dimensional stability, mechanical and thermal properties of the impregnated SC-CTL were analyzed according to the standards. The results showed that the impregnation of BL/PF resin into SC-CTL have improved the coconut wood’s dimensional stability, mechanical and thermal properties. The morphology of coconut wood’s cells loaded with BL/PF resin clearly showed a full penetration. The results also suggested that the addition of 20% BL/PF resin was sufficient to enhance the dimensional stability, mechanical and thermal properties of SC-CTL. Thus, it is evident that the BL has the potentiality to be used as impregnant in SC-CTL through impregnation with vacuum-pressure method.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Black liquor,Coconut wood,Flexural strength,Impregnation,Tensile strength[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: ‘The authors would like to thank the Ministry of Research, Technology and High Education (RISTEKDIKTI), Indonesia, for providing Research Grant No. 127/SP2H/PTNBH/DRPM/2018.
