During production or storage, we should store photochromic powders in dry and dark place to avoid light fatigue. We should also ensure there is no corrosive substance such as strong acid or alkali in the environment. We should not use it with UV absorber. Different additive or base material may cause unexpected effect of the product. Due to the variety of types, usage status, and application environment of photosensitive materials, it is not possible to list them all.
