All the data given in this table elaborated carefully and are based on our experience and you can rely upon them. We cannot however, takeresponsibility for the resault obtained becuse they depend mostly on fabric used and the local conditions of dyes application, and on concentration ofthe dye used and the amount of dyeing assistant.

Application

OBA for paper industry, especially recommended, when high whiteness level is demanded, in surface sizing and coating pigment pastes method. Very good resistance to acid and alkaline factors, allows for the use of this optical brightener regardless of the pH range. Because of low substantivity, the optical brightener is not recommended for brightening paper in the mass.
