Product Description
Product Introduction:

Optical Brightener OB-T belonging to coumarin compounds, insoluble in water, odorless, and stable in performance.Due to its superior fluorescent whitening effect, good thermal stability, and minimal addition, the fluorescent whitening agent OB-T can be used in conjunction with dyes to produce special brightness, which is particularly effective in color formulations.

Purpose:

Mainly used for whitening plastics, colorants, rubber, polyester, polyamide, and polyacrylonitrile fibers. Such as PVC, PS, ABS, PE, PP and other plastics.

2. Special whitening properties.
3. Good photostability and low volatility.
4. Non toxic and odorless.
