dc.description.abstract In the present study, we used tensile shear tests, Shore hardness tests, differential scanning calorimetry (DSC), and thermogravimetry (TGA) to characterize a reactive polyurethane-based hot melt adhesive. We also measured contact angles at various temperatures to evaluate the wettability of the adhesive and to determine the optimum temperature range for applications. The adhesive was tested following curing for various times, and the bonding of the adhesive with several materials was investigated to determine whether it has the potential for greater versatility of application. Therefore, we explored new uses of the adhesive, such as in the matrix of a composite with fiberglass. Reactive hot melt adhesives are useful because they provide a certain degree of flexibility to joints, and have high processing speeds, high initial rigidity, and high working temperatures.
dc.description.abstract En el presente estudio, se caracterizó un adhesivo termofusible reactivo de base poliuretano mediante ensayos de cizalladura a tracción, dureza Shore, calorimetría de barrido diferencial (DSC) y termogravimetría (TGA). También se midieron los ángulos de contacto a diferentes temperaturas para evaluar la mojabilidad del adhesivo y seleccionar el mejor rango de temperatura de aplicación del adhesivo. Se caracterizó el adhesivo a diferentes tiempos de curación y se evaluó la unión del adhesivo con diferentes materiales adherentes, para proporcionar una mayor versatilidad de aplicaciones, con el fin de explorar nuevos campos de utilización de estos adhesivos como matriz en materiales compuesto con fibra de vidrio. La importancia de utilizar adhesivos termofusibles reactivos se debe a sus uniones con cierta flexibilidad, altas velocidades de procesamiento, elevada rigidez inicial y soportan altas temperaturas de trabajo.
