Molecular Formula:C17H31NO4
Molecular Weight:3100-4000
CAS No.:65447-77-0
Properties
A polymerized hinderer amine light stabilizer
Low volatile, mobility is low, it has good compatibility with materials; In the material with pigment, the application effect is better than ultraviolet absorbent;It can also improve the thermal oxygen aging resistance of the material.
Application
It is widely used in polyolefin and its copolymers such as EVA and polypropylene blends with elastomers. In addition, UV-622 is very effective in polyacetal, polyamide and polyurethane applications. When used together with other photostabilizers, it has a synergistic effect and can effectively prevent the photoaging of the polymer, providing excellent photostability and long-term thermal stability for the polymer.
Storage
Keep container tightly closed in a cool, well-ventilated place.
The recommended max. storage life is 12 month when stored under normal conditions.
