Maltodextrin is a potential natural adhesive for particleboard because it is reactive and freely soluble in water. However, maltodextrin has a low water resistance and a high melting point that hinder its development as a particleboard adhesive. An addition of ammonium dihydrogen phosphate (ADP) as a catalyst of maltodextrin was expected to overcome its weaknesses. The optimal pressing temperature was expected to be affected because the addition of catalysts affects the melting point. This research aimed to investigate the effect of maltodextrin/ADP ratios and pressing temperatures on particleboard properties made from Salacca frond. The maltodextrin/ADP ratios used in this research were 100/0, 90/10, and 80/20 wt%, and the pressing temperatures were set at 200 and 220 °C. The combination of an increased ADP ratio in maltodextrin and an increased pressing temperature improved the particleboard properties. The ADP addition in the maltodextrin lowered the onset temperature and caused weight reduction in the adhesive-sprayed particles, but increased the thermal stability of the mats at temperatures above 350 °C compared to mats with 100% maltodextrin. The results suggested that a maltodextrin/ADP mixture could be a promising particleboard binder.
