Ultra-high Solubility Optical Brightener OB

Highly dispersible,designed to achieve high loading.It can be dissolved instantly in the solvent and keep clear and transparent for a long time. Its solubility is more than two times that of traditional optical brightener OB.Solvent-free pigment paste can also be added.

1.In organic solvent:The Super high solubility optical brightener OB can reach 11%-16%.

While that of traditional optical brightener OB is only 6%-8%.

2.Good price.

3. Very high light&weather fastness, high whiteness, no yellowing.

4. Insufficient dispersion of pigments will lead to uneven color and other surface defects. So ultra-high solubility OB are very suitable for pigment paste/ink/paint/coating.

5.Ultra-high solubility makes it easier to disperse and disperse more evenly,Higher pigmentation levels will provide high color strength, gloss and lasting durability.

It is also suitable for plastic masterbatch and plastic filled masterbatch. In the field of plastics, thermoplastics, thermosetting plastics,general plastics and various engineering plastics have good whitening performance, weather resistance stability. In the field of pigment paste/ink/paint/coating/Silicone sealant, it mainly improves the whiteness and brightness, improves the grade of products, improves the wetting effect of products, and has long-lasting fluorescence intensity, making the products durable.
