UV770 NEW

Light Stabilizer 770, often referred to in technical contexts as LS 770, is a chemical used in the stabilization of various polymers against the effects of ultraviolet (UV) light. This stabilizer is particularly useful in preventing the degradation of materials exposed to UV radiation, which can lead to discoloration, loss of strength, and other forms of deterioration.

The chemical name for Light Stabilizer 770 is Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate, and it is commonly used in plastics and coatings to enhance their durability and lifespan, especially when they are used in outdoor applications where exposure to sunlight is a significant factor.

LS 770 is part of a class of light stabilizers known as Hindered Amine Light Stabilizers (HALS). These stabilizers work by scavenging free radicals formed in polymers when they are exposed to UV light. This action helps to interrupt the degradation process that the polymers would otherwise undergo due to UV exposure.

In terms of applications, Light Stabilizer 770 is used in various industries, including automotive, construction, and consumer goods, where materials are regularly exposed to sunlight and require protection to maintain their integrity and appearance over time.
