Reactive Yellow 18 is a dichlorotriazine (DCT) reactive dye, commonly known as a “hot brand” dye. It is specifically designed for dyeing cellulosic fibres at higher temperatures (approx. 80°C), where it exhibits maximum reactivity and fixation. It produces a bright, greenish-yellow shade and is valued for its good lightfastness and stable performance in high-temperature exhaust dyeing processes, making it a reliable choice for deep and durable shades.
