BUITRAGO-SUESCUN, Oscar; PALACIO-LEON, Oscar  e  DELGADO-TOBON, Arnoldo. Evaluation of two silanes in ethylenevinylacetate and TelinneMonspessulana flour compounds. Ingeniería Mecánica [online]. 2015, vol.18, n.3, pp. 166-172. ISSN 1815-5944.

A comparative study the effect of the addition of silane coupling agents, vinyltrimethoxysilane and 3-aminopropyltriethoxysilane on ethylenevinylacetate and Telinnemonspessulana flour composites was performed. The silane coupling agents were added in the mixing stage of ethylene vinyl acetate and wood flour (untreated and mercerized). Tests were also made by mixing ethylenevinylacetate with previously grafted wood flour. Flour graft was performed with vinyltrimethoxysilane and 3-aminopropiltrietoxisilano. The compounds were tested for tensile testing to evaluate the coupling agents. It was found that the addition of amino-silane during mixing increased tensile strength, being this an important result since these are lightweight materials that can be used in the construction and automobile industry.
