Abstract

Abstract - Cashew nut shells is a waste in the cashew nut processing industry. The cashew nut shell is processed into liquid smoke by pyrolysis method. This liquid smoke can be used as a substitute for synthetic phenol. Phenol is the raw material of phenolic resin in the manufacture of varnish. This research aimed at determining the varnish characteristic obtained from the optimum condition of cashew nut shells pyrolysis by studying the effect of the addition of 0%, 10% and 20% commercial varnish at pyrolysis temperatures of 200 and 300o C. The results were obtained at 300° on 0% commercial varnish addition with the density of 1.0024 gr / ml, 1 hour pseudo drying time and 2.45 hours of hard drying time. After the addition of (10-20)% commercial varnish, it was found that the addition of 20% commercial varnish was the best condition in which volatile matterl rate, density, touch dry time and hard dry time were of 45.51%, 1.05 (g / ml), 2.55 hours and 5.35 hours, respectively. All characteristics were meeting the Indonesian National Standards (SNI) for varnish type A (for interior and exterior use). This research indicated that the liquid smoke produced from the pyrolysis of cashew nut shells was a potential alternative material to be used as compound or substitute phenol in varnish manufacture. Keywords: Pyrolysis, Varnish, volatile
