Navy Blue / 150% Conc
Reactive Blue ME2RL is a reddish-navy blue bifunctional dye. It is the global standard for achieving dark navy shades on cotton. As a High Exhaustion (HE/ME) class dye, it offers high fixation yields and excellent compatibility with Yellow 145 and Red 195 for creating tertiary shades.
Reactive Blue 194 contains both Vinyl Sulfone (VS) and Monochlorotriazine (MCT) reactive groups. This dual reactivity allows it to bond to the fiber over a wider range of temperatures (60°C - 80°C) and makes it less sensitive to variations in salt or alkali concentration.
High concentration grade for maximum depth of shade.
