SperseBright OB-1 is a fluorescent brightening agent used to whiten engineering plastics, including polyester, polycarbonate, and styrenics. It provides superior Ganz whiteness in PC, PET, PS, and PMMA at concentrations as low as 100 ppm. SperseBright OB-1 can be used alone or in combination with SperseStab hindered amines, antioxidants, and selected UV absorbers.

SperseBright OB is ideal for adhesives, coatings, acrylics, and urethanes, as well as rigid and plasticized PVC. It is a heat-resistant, solvent-soluble, and chemically stable fluorescent whitener supplied in a fine powder form that is easier to dissolve and/or disperse compared to conventional product forms of larger particle sizes. This form is ideal for screen-printing and coating applications. SperseBright OB can be used in combination with antioxidants and certain UV stabilizers that absorb UV-B radiation.
