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.
