Product Description:
Ranbar GS1409N colorless to brown-red irreversible photochromic pigment is a special pigment. The pigment is processed by microcapsule coating technology and has a diameter of 2-5um. The appearance is powdery and there is a protective coating layer on the surface. The film layer can protect the photochromic pigment from damage to its molecular structure due to high temperature, oxidation, etc., and has good stability and durability.
