optical brightener 184

タイトルまたは説明

PROPERTIES:
    Optical brightener OB is a kind of benzoxazole compound, lt is odorless, hard to dissolve in water, soluble in paraffin, fat, mineral oil, wax and common organic solvents. It can be used for whitening thermoplastic plastics, PVC, PS, PE, PP, ABS, Acetate fiber, paint, coating, printing ink, etc. It can be added at any stage in the process of whitening the polymers and make the finished products emitt a bright bluish white glaze.
    It can also be used as special marks in identify fakless material if used in printing ink.

DIRECTION FOR USAGE:
    Thoroughly dispersed in all those polymers.If any ultral violet spectrum absorption agent is used in the polymers, the optimal dosage of optical brightener OB should be adjusted.
DOSAGE: (per **0 kg polymer ):
    PVC white 0.***0.*5% (****0 g) transparent 0.*****0.**1% (0.**1 g)
    PS white 0.**1% (about 1g ) transparent 0.*****0.**1% (0.**1 g)
