3. Aplicaciones recomendadas<\/strong><\/p>\n

Gracias a su buena relaci\u00f3n calidad-precio y a su intenso color rojo, el PR21 se utiliza ampliamente en:<\/p>\n

Pinturas y recubrimientos industriales:<\/b><\/strong>\u00a0Sistemas de secado al aire, imprimaciones.<\/p>\n

Tintas de impresi\u00f3n:<\/b><\/strong>\u00a0Especialmente para tintas de empaque y otras aplicaciones en las que no es fundamental una alta resistencia a la luz.<\/p>\n

Pl\u00e1sticos:<\/b><\/strong>\u00a0Coloraci\u00f3n de PVC, LDPE y otros pol\u00edmeros procesados a temperaturas moderadas.<\/p>\n

Productos de oficina y papeler\u00eda:<\/b><\/strong>\u00a0Tintas, t\u00f3neres y l\u00e1pices de colores.<\/p>\n
