Precautions	1. The most suitable selecting base material’s PH value should be 7~9. 2. Photochromic materials’ light fatigue occuring because of high humidity and excessive UV light exposure, it is recommended to add light absorber and antioxidant to reduce its light fatigue. 3. While using additives, such as antioxidant, heat stabilizer, UV light absorber and inhibitor, to increase the light fatigue of the photochromic material, the additives’ adding ratio is based on the using media set, error ratio will accelerate light fatigue. 4. Photochromic material do not contain any harmful substance to human, it meet the safety standards of toys and food packaging. 5. Temperatures resistance: 220 centigrade.
