622Tinuvin

Tinuvins are additives that protect the coating from UV rays and make it more durable.

UV rays can cause the coatings to fade and crack, which will cause the coatings to become more permeable to water and chemicals.

Exposure to sunlight can have an adverse effect on the durability of plastic parts because the ultraviolet rays from the sun break the chemical bonds in the polymer that cause the surfaces to fade.

Through the following three mechanisms, thinoviruses counteract the following processes:
1) Screening or filtering UV rays
2) Absorption of ultraviolet rays from sunlight
3) Extinguish the excited state
