Function:
Highly efficient whitening: Fluorescent whitening agent KS-N can strongly absorb ultraviolet light and convert it into blue-purple fluorescence, which complements the yellow light originally existing on the surface of the treated object, thereby achieving an efficient whitening effect and making the object appear white and bright.
Improve the brightness: Through the emitted fluorescence, it can not only whiten, but also enhance the color brightness of the treated object, making white objects whiter and purer, and colored objects more vivid and vivid, improving the overall visual effect.
Good light resistance and stability: It has good light resistance, is not easy to decompose or fade under light conditions, and can maintain the whitening effect for a long time. At the same time, it can maintain relatively stable chemical properties under different environmental conditions and treatment processes to ensure the continuous performance of the whitening function
Application:
Coating and ink industry: Using fluorescent brightener KS-N in coatings and inks can improve the whiteness and glossiness of coatings and printed products, making white coatings whiter and purer, and color inks more vivid and eye-catching, thus enhancing the visual effects and artistic appeal of printed products. It is widely used in advertising printing, packaging printing and other fields.
