The aim of this study was to determine the usability of selected natural dye extracts as environmentally friendly colorants that are used in painting of MDF based furniture and evaluate their resistance to scratch resistance, adhesion resistance, and surface hardness properties. In this study, the water-based lacquer coatings were prepared with natural dyes obtained from purple cabbage (Brassica oleracea), safflower (Carthamus tinctorius L.), Red beetroot (Beta vulgaris L.) and three synthetic paints that were black, blue and light blue as a comparison. Coated MDF test panels used for evaluation of performances of dyes to abiotic factors that are determined by mechanical tests such as scratch resistance, adhesion resistance, and surface hardness. As a result of the study, it has been observed that, except for scratch resistance, natural dyes perform as well as synthetic ones as alternative colorants in the lacquer coatings. Thus, natural and aesthetic raw materials that are environmentally friendly dyes can be used safely especially in children's furniture and for wood-based products that are especially used indoors., El objetivo de este estudio fue determinar la usabilidad de extractos de tintes naturales seleccionados como colorantes ecológicos que se utilizan en la pintura de muebles a base de MDF y evaluar su resistencia al rayado, la resistencia a la adhesión y las propiedades de dureza de la superficie. En este estudio, los recubrimientos de laca al agua se prepararon con colorantes naturales obtenidos de col morada (Brassica oleracea), cártamo (Carthamus tinctorius L.), remolacha roja (Beta vulgaris L.) y tres pinturas sintéticas que eran negro, azul y azul claro como comparación. Paneles de prueba de MDF revestidos utilizados para evaluar el rendimiento de los tintes frente a factores abióticos que se determinan mediante pruebas mecánicas como la resistencia al rayado, la resistencia a la adhesión y la dureza de la superficie. Como resultado del estudio, se ha observado que, a excepción de la resistencia al rayado, los tintes naturales funcionan tan bien como los sintéticos como colorantes alternativos en los recubrimientos de laca. Por lo tanto, las materias primas naturales y estéticas que son tintes ecológicos se pueden utilizar de forma segura, especialmente en muebles para niños y para productos a base de madera que se utilizan especialmente en interiores.
