Défauts dus au séchage
Ease of Drying: The wood dries fairly slowly, with only slight seasoning defects. In Malaysia it takes 2.5 to 3 months to air dry 15 mm thick boards. Drying Defects: Cupping, bowing, end checking, splitting and staining are reported. Kiln Schedules: In Papua New Guinea a kiln schedule with a dry-bulb temperature of 55 to 71 degrees gave acceptable results for the wood of this species. Using this schedule the wood can be dried from 65% to 15% moisture to 15% moisture content in 6 days.
