Production description
Brightener SD-4074 is a stilbene derivative with high whiteness and wide application range. It is a fluorescent whitening agent suitable for whitening cotton and its blended fabrics
Characteristic and advantages
1.Suitable for whitening, bleaching and brightening in the same bath.
2. High whiteness, strong fluorescence, less dosage, not easy to be stained, and easy to change materials.
3. Used in the bleaching of cellulose fiber, regenerated cellulose fiber and nylon fiber,special white processing technology.
4. At the same dosage, higher whiteness can be obtained than ordinary whitening agent
5.Wide range of pH value.
6. The dyeing temperature range is wide, and it is stable in hydrogen peroxide water.
7. It has good resistance to yellowing at high temperature.

Application range
SD-4074 is best to adjust the slurry with cold water, and then dissolve with 80 ºC hot water to obtain a uniform solution, and then add it to the application bath or supplement liquid.
