  • Applications

    C.I. Pigment Red 88, CAS 14295-43-3, is a high-quality red pigment used in coatings and printing inks to deliver bright, color-stable red. It is also commonly incorporated into plastics and rubber to color polymer products, and is utilized in textiles to achieve color depth on fibers. Additionally, the pigment may be considered for cosmetic and personal care formulations, as well as for adhesives to obtain a uniform red color in bonds and coatings.
