The optical brightener KSN has a similar chemical structure to optical brightener OB-1, but it has a better whitening effect on polyester fibers and plastic products than optical brightener OB-1, and it has better compatibility with plastics than OB-1, and it is used in a small amount.It Can produce very good whitening effect, which is far from optical brightener OB-1.
The brightening effect of optical brightener KSN is very good, and it enjoys the reputation of the king of whitening in China, and is often used in high-end plastics that require high whiteness.
The optical brightener KSN is a benzoxazole compound. It is an excellent upgrade product among many optical brighteners. It has a blue-violet color and excellent light resistance. It is suitable for all plastics, especially in synthetic fibers. At the same time, it can also be used for whitening and brightening color materials in coatings, paints, inks and other industries. The optical brightener KSN has the characteristics of convenient application, minimum dosage and best effect.
