The coating auxiliary brightening agent Optical Brightener OB For Oil-based Coatings is optical brightener OB, and it’s usually used with titanium dioxide, can enhance the whiteness and brightness、transparency of the coatings , but also to prevent the coatings yellowing, fading.

Optical Brightening Agent OB has excellent weather resistance, migration resistance and high stability. It is widely used in plastics such as PVC, PP, ABS, PE, PS, EVA, and PMMA, rubber, coating, painting, ink and plastics staple fiber etc.

Optical Brightener EBF can be used in the production of commercial brightener-EB, as well as in the whitening of various polyolefin plastics, ABS engineering plastics and organic glass to make their colour brighter and whiter. Optical Brightener EBF Pure Powder 99%min with CAS No 2866-43-5/12224-41-8

Ultramarine Blue is a saturated, semitransparent, dark, violet-leaning blue.Ultramarine is a complex sodium silicate containing sulfur and aluminum with the chemical formula Na7Al6Si6O24S3. The intense and distinctive blue color is caused by the unpaired electrons in the sulfur radical anion s3-. Ultramarine has heat and alkali resistant properties. It is chemically stable under normal conditions and resistant to high temperatures.The pigment is also resistant to alkaline solutions and can therefore be used in frescoes. It is usually be used as a colourant and optical brightener for plastics, rubber, inks, color painting, textiles, paper, cosmetics, detergents, cement and architecture.Ultramarine's unique property of flocculation—the tendency of its particles to clump up together—give it a lively granulating texture in washes. Ultramarine Blue Purity 99%min with CAS No 57455-37-5.

Whitening Masterbatch is a kind of color masterbatch, commonly known as plastic colorant, is an additive on plastic, mainly plays the role of whitening. Most of the masterbatch manufacturers will add white masterbatch whitening agent, this can avoid the raw material stirring, avoid uneven stirring resulting in the appearance of the finished product not beautiful. At the same time, downstream plastic products no longer need to use fluorescent whitening agent alone.The following is about Masterbatch Whitening Agent OB-1.

Optical Brightener OB For Recycled Plastic, Fluorescent brightener OB, 2,5-Di (5-tert-butylbenzoxol-2-yl) thiophene, fluorescent whitening agent 184, fluorescent brightener 184, as plastic additive has obvious whitening effect on recycled plastics, especially transparent recycled plastics.CAS No. 7128-64-5, molecular formula C26H26N2O2S, is a highly purified optical brightener powder with very excellent weather resistance, very excellent migration resistance and very high stability.
