The coating auxiliary  brightening agent of oil coatings is optical brightener OB, and it’s usually used with titanium dioxide. 
Oil-based coatings are widely used in building exterior wall coatings, interior wall coatings, household coatings, industrial machinery surface coatings, ships, automobiles and other fields. The optical brightener OB can be used for brightening various normal or low temperature paints, inks, coatings and solvent-based acrylic, epoxy, amino, varnish, UV varnish, color paste and high-grade plastic products.
