In plastics, the amount of fluorescent whitening agent is usually expressed as a percentage relative to the mass of the plastic.
The usual amount of transparent plastic is 0.0001%-0.001%, and the amount of white plastic is usually 0.05%-0.1%.
In paint and ink, the amount of fluorescent whitening agent is usually 0.02%-0.05%. When it comes to the specific dosage, it is recommended to get some small samples from the fluorescent whitening agent manufacturer, because less fluorescent whitening agent will easily cause whitening.The effect is unsatisfactory. Using too much will cause the brightener to separate out, so before determining
the dosage, take a sample test to achieve our desired effect.
