{Properties} :                                

    BBU liquid brightener is a compund of pure product and synergist, belongs to the derivation of di-thyrenc quar-sulfonic. Its structure is same kind as the brightener produced by the Ciba company of Swiss. Molecule structure is:
    The product is a substitue for VBL brightener used in the pruduct line in large-scale paper making factory, which can withstand becoming yellow ofpaper products and is better than the same kind of products existing in market in brighten efficiency and standing against disadvantage interfere, especially adapt to use in the modern large-scale paper making line. It receives good praise from the consumer.

{Stability under low temperature}:
    Effect remains after melting the solidification appeared if it is stored under freezing point for a long time. Fastness: withstand sunlight, acid, alkali.

{Storage}:                                      

    Prevent from sunlight and not allowed to meet with cation compound(such as: aluminum sulfate, cation resin, etc).

{Package}:                                    
    Plastic drum lined with plastic bag, weight:50KG,1t polythene plastic drum, or according to the need of consumer.
