Performance Characteristics
1. Anionic, can be used in the same bath as anionic surfactants or dyes, non-ionic surfactants and hydrogen peroxide.
2. Not suitable for use in the same bath with cationic surfactants or dyestuffs.
3. Fluorescent Brightener VBL is stable to insurance powder.
4. Fluorescent Brightener VBL is not resistant to copper, iron and other metal ions.
1. For printing and dyeing, dosage: 0.08-0.3%, bath ratio: 1:40, best dyeing bath temperature: 60ºC, PH 7-9, dyeing time 20-30 minutes.
2. For paper making, dissolve in 80 times water and add to pulp and paint, the dosage is 0.1-0.3% of the dried pulp or dried paint.
Storage and Notes
