In recent years, the demand for paint in the decoration field has continued to rise, and consequently the demand for paint Optical brightener OB 184 CAS NO.7128-64-5 has risen. Optical brightener OB 184 CAS NO.7128-64-5 is a model with a relatively resonable price compared with other optical brighteners. Its main function is to increase the whiteness and vividness of the paint surface. It emits blue fluorescence by absorbing the invisible ultraviolet light, which combines with the yellow light of the paint itself to form white light.
There is also a common whitening product in paint is titanium dioxide, but its whitening principle is completely different from that of Optical brightener, which is a physical covering.
