[ application ]
Fluorescent brightener OB due to its superior fluorescent whitening effect, good thermal stability, adding small amounts of characteristics, especially suitable for paint, glue, paint, printing ink cold whitening (room temperature directly mix, or slightly heating).
The fluorescence whitening agent OB can be used with dye to produce special brightness, which is particularly effective in color formulation.
Appearance
Yellow or yellow-green crystalline powderUsage
The amount of OB (reference dosage) for each 100kg of polymer
Glue: white 0.1 ~ 0.5% (10g-50g)
Paint: white 0.2 ~ 0.5% (1g)
Transparent 0.01 -- 0.01% (0.1g-1g)
Ink: white 0.1-0.5% (10g-50g)
The dosage may refer to the above examples. When adding any uv absorber to the polymer, it is important to adjust the optimum dosage of the fluorescence brightener OB.
