Aplicaciones principales<\/h3>\n

Disolventes industriales (uso principal):<\/strong> El MAC es un disolvente de evaporaci\u00f3n r\u00e1pida para lacas de nitrocelulosa, resinas acr\u00edlicas y recubrimientos de poliuretano. Garantiza una r\u00e1pida formaci\u00f3n de la pel\u00edcula, mejora el brillo y la adherencia del recubrimiento, y se utiliza ampliamente en el repintado de autom\u00f3viles, los recubrimientos para madera y los acabados de muebles. Tambi\u00e9n se utiliza como disolvente en tintas de huecograbado y flexograf\u00eda, mejorando la imprimibilidad y la intensidad del color.<\/p>\n

Adhesivos y selladores:<\/strong> Se utiliza como disolvente para adhesivos de contacto, adhesivos sensibles a la presi\u00f3n y adhesivos termofusibles, especialmente para la uni\u00f3n de pl\u00e1sticos, caucho y madera. Su baja toxicidad y su r\u00e1pida velocidad de evaporaci\u00f3n reducen las emisiones de COV y mejoran la eficiencia de la producci\u00f3n.<\/p>\n

Intermedio de s\u00edntesis qu\u00edmica:<\/strong> Una materia prima fundamental para la producci\u00f3n de anh\u00eddrido ac\u00e9tico mediante carbonilaci\u00f3n, que se utiliza ampliamente en la s\u00edntesis de productos farmac\u00e9uticos, pesticidas y acetato de celulosa. El MAC tambi\u00e9n se hidroliza para producir \u00e1cido ac\u00e9tico y metanol de alta pureza, y sirve como agente metilante en la s\u00edntesis org\u00e1nica.<\/p>\n

Agente de extracci\u00f3n:<\/strong> Se utiliza en la extracci\u00f3n de productos naturales (por ejemplo, aceites esenciales de plantas, aromas y fragancias) debido a su buena solubilidad y a que deja pocos residuos. Tambi\u00e9n se emplea en la separaci\u00f3n de hidrocarburos y en la purificaci\u00f3n de compuestos org\u00e1nicos en entornos de laboratorio.<\/p>\n

Producto de limpieza:<\/strong> Se utiliza como agente desengrasante para componentes electr\u00f3nicos, instrumentos de precisi\u00f3n y superficies met\u00e1licas, ya que disuelve eficazmente la grasa, la cera y los residuos org\u00e1nicos sin provocar corrosi\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
