VAT Blue is a synthetic vat dye known for its brilliant and durable blue color. It is primarily used in the textile industry for dyeing cellulose fibers such as cotton, rayon, and linen. VAT Blue is valued for its excellent fastness properties, including resistance to washing, light, and rubbing, making it ideal for high-quality fabric applications. This dye undergoes a reduction-oxidation process during application, allowing it to penetrate fibers deeply and produce vibrant, long-lasting blue shades. Besides textiles, VAT Blue is also used in leather dyeing and specialty coatings requiring stable blue pigmentation.
