Se presenta como un l\u00edquido incoloro y transparente con un olor intenso y dulce, similar al de la acetona. Como uno de los disolventes cet\u00f3nicos industriales m\u00e1s utilizados, el MEK destaca por su gran poder disolvente, su r\u00e1pida velocidad de evaporaci\u00f3n y su buena compatibilidad con diversas resinas y compuestos org\u00e1nicos, lo que lo convierte en un producto imprescindible en las industrias de recubrimientos, adhesivos y s\u00edntesis qu\u00edmica.<\/p>\n

Aplicaciones principales<\/h3>\n

Recubrimientos y pinturas industriales:<\/strong> El MEK es un disolvente fundamental para las lacas de nitrocelulosa, las resinas alqu\u00eddicas, las resinas acr\u00edlicas y los recubrimientos de poliuretano. Su r\u00e1pida velocidad de evaporaci\u00f3n garantiza una r\u00e1pida formaci\u00f3n de la pel\u00edcula y mejora el brillo, la adherencia y la durabilidad de las capas de recubrimiento. Se utiliza ampliamente en el repintado de autom\u00f3viles, los recubrimientos para madera y las pinturas para mantenimiento industrial.<\/p>\n

Adhesivos y selladores:<\/strong> Se utiliza como disolvente para adhesivos de contacto, adhesivos a base de caucho y selladores estructurales. Disuelve eficazmente el caucho, las resinas y los pol\u00edmeros, lo que permite una fuerte uni\u00f3n de materiales como la madera, el pl\u00e1stico, el cuero y el metal.<\/p>\n

S\u00edntesis qu\u00edmica:<\/strong> Un producto intermedio vers\u00e1til para la producci\u00f3n de metilisobutilcetona (MIBK), metilisobutilcarbinol (MIBC) y productos farmac\u00e9uticos (por ejemplo, antibi\u00f3ticos y analg\u00e9sicos). Tambi\u00e9n se utiliza como disolvente en la fabricaci\u00f3n de pl\u00e1sticos, fibras sint\u00e9ticas y caucho.<\/p>\n

Limpieza y desengrasado:<\/strong> Se utiliza como limpiador a base de disolvente para eliminar grasa, cera, pintura y tinta de equipos industriales, maquinaria y componentes electr\u00f3nicos. Tambi\u00e9n es un ingrediente clave en los diluyentes de pintura y los quitaesmaltes.<\/p>\n

Uso en laboratorio y an\u00e1lisis:<\/strong> Se utiliza como disolvente en cromatograf\u00eda y en la preparaci\u00f3n de muestras para el an\u00e1lisis de compuestos org\u00e1nicos, gracias a su gran poder de disoluci\u00f3n y a su bajo punto de ebullici\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"

La metiletilcetona, conocida com\u00fanmente por sus siglas MEK y cuyo nombre sistem\u00e1tico es butanona, es una cetona alif\u00e1tica vol\u00e1til e inflamable con la f\u00f3rmula qu\u00edmica C4<\/sub>H8<\/sub>O (f\u00f3rmula estructural: CH3<\/sub>COCH2<\/sub>CH3<\/sub>) y n\u00famero CAS 78-93-3.
