The effect of amino silane coupling agent on properties of  wheat straw boards produced by UF and MF resins, was investigated in this study. For producing the straw boards small particles of straw were used . The results showed that adding 2 and 5 percents of silane had significant effect on improvement of boards properties. This improvement might be due to surface treatment of wheat straw particles with silane coupling agent by  increasing the bondability between straw particles and resin. The more amine groups in  Melamine Formaldehyde resin compare to urea formaldehyde resin , lead to an improvement in  bending strength and thickness swelling.
