3.The adding methods of optical brighteners:

According to the different producing techniques of paints, there are two ways of adding optical brighteners:

(1) Optical brighteners OB-1 are usually added in powder form during the grinding process (also the preparation process of paste) of paints production, then grinded together with paint vehicle. After fully grinded to microparticle with diameter ≤20μm, evenly disperse it into paints.

(2) After levigating optical brighteners OB-1, add it into paints by high-speed dispersion machine.

4. Packaging And Storing:

optical brightener OB is in 10Kg/25Kg/50Kg Carton Drums. Stored In Dry And Cool Condition.
