Abstract	The effect of vinyltrimethoxysilane- and γ-aminopropyltriethoxysilane-treated nanosilica and untreated nanosilica particles as fillers on practical properties of urea formaldehyde-bonded plywood was evaluated. Nanosilica used in two different contents (1 and 2 %). The results of FT-IR spectroscopy revealed that both silane coupling agents can well treat the nanosilica particles. The least water absorbtion and thickness swelling observed in the case of boards with 1 % treated nanosilica with vinyltrimethoxysilane, and those with γ-aminopropyltriethoxysilane had the best bending strength and modulus of elasticity. The higher shear strength found for boards with 2 % treated nanosilica by 1 % vinyltrimethoxysilane. Overall, in comparison with the common filler used in plywood production, namely wheat flour, nanofillers had a greater improving effect on the plywood properties. The effect of vinyl silane and amino silane on properties of plywood is different with each other because of their different constructions. The vinyl silane had a better performance than the amino one to improve the physical properties (2 and 24 h water absorption and thickness swelling) and shear strength of the produced boards but the latter showed a higher increasing impact on the modulus of elasticity and rupture. The results showed that 1 % nanosilica had proper enough effect on properties of plywood panels and even in some cases had better effect than 2 % nanosilica content.
