Photosensitive Dye – Ranbar Gray DP0080

Ranbar DP0080 colorless to gray photosensitive dye is a spirooxazine organic compound dye that turns dark gray when exposed to sunlight or ultraviolet light, and returns to its natural or colorless state when removed from sunlight or ultraviolet light.

Ranbar Photosensitive dye itself will not change color when it is exposed to light, and needs to be dissolved in other suitable carriers to achieve photochromic effect. It has the advantages of obvious color change and good fatigue resistance. It can be completely dissolved in the carrier and presents a high transparency state, so as to realize the effect of complete light transmission of the system and effectively ensure the transparency of injection molding products. It can be widely used in industries such as plastics, coatings and inks.

Product Application:
Simply add the Photosensitive dye to the base material and mix thoroughly. The lower the ratio mixed into the medium, the more transparent it will appear in a colorless state or in thin layers. The key is to experiment with the mixing ratio to find the proportion that best suits your specific application. It is recommended to start with a smaller amount and gradually add more until the desired color is achieved. A ratio of 1 part Photosensitive dye to 20 parts base material is a good starting point. It is important to note that mixing generates heat, which may temporarily alter the color of the mixture!
