dc.description.abstractEste trabajo se enfoca en ofrecer recursos técnicos para la correcta selección de un agente dispersante dirigido a formular concentrados pigmentarios universales que sean compatibles en sistemas de recubrimientos base agua y base solvente – alquídicos. El desarrollo de este trabajo contempla una clasificación de los agentes dispersantes disponibles en el mercado colombiano, y una caracterización por espectroscopía infrarroja para hacer una primera selección de los agentes dispersantes que ofrecen características de universalidad. En este primer paso se selecciona un dispersante oligomérico de poliéster modificado y un dispersante acrílico de bloques AB. Una vez caracterizados los grupos funcionales se realiza un diseño de experimentos factorial 32 para la determinación de la relación óptima de concentración de pigmento y dispersante. Finalmente, con los concentrados pigmentarios formulados con la relación óptima, se realizan ensayos de estabilidad y compatibilidad para evaluar el desempeño ofrecido por el dispersante. Los datos experimentales obtenidos presentan que el dispersante oligomérico posee una mayor compatibilidad en medios acuosos y solventes que el dispersante acrílico por bloques
dc.description.abstractThis work focuses on providing technical resources for the proper selection of a dispersing agent aimed at universal pigment concentrates that are compatible in water-based and solvent-based coatings. The development of this work includes a classification of dispersing agents available in the Colombian market, and a characterization by infrared spectroscopy to make a first selection of dispersing agents that offer universal characteristics. In this first step, a modified polyester oligomeric dispersant and an AB block acrylic dispersant are selected. Once the functional groups are characterized, a 32 factorial design of experiments is carried out to determine the optimal pigment concentration and dispersant ratio. Finally, with the pigment concentrates formulated with the optimal ratio, stability and compatibility tests are carried out to determine the performance offered by the dispersing agent. The experimental data obtained shows that the oligomeric dispersant has greater compatibility in aqueous and solvent media than the acrylic dispersant.
