Gluability of a veneer species is a function of the strength and durability of plywood. Champa has been one ofthe chosen decorative species for veneer. An investigation was made to find the gluability of Champa compared to that of Civit, a species having excellent gluability properties. Champa veneers peeled to 1.0 mm thickness and dried to 8% target moisture content were bonded with liquid UF glue catalysed with 2% hardener and extended with 20% wheat flour to make 3-ply plywood panels. The dry shear load and wet shear load of Champa plywood compared favourably with those of Civit plywood and the values were well above the minimum requirements. Therefore, plywood made from Champa veneer bonded with U F glue may be recommended for use as Warm Water Resistant Grade.
