Application
The hindered amine light stabilizer has better light stability than the general ultraviolet absorber, and can improve the heat resistance together with the antioxidant, further improve the aging resistance, has good compatibility with the polymer, and is excellent in heat stability. High temperature processing provides maximum protection for the polymer and reduces UV damage.
This product is odorless, has no effect on the original odor of the polymer, has no effect on the original color of the substrate, and has synergistic effect with other ultraviolet light absorbing agents.
As a light stabilizer, this product is suitable for polyethylene, polystyrene, polypropylene, ABS resin, polyester and polyurethane. It is recommended to add 0.1-0.5%.
When used in combination with an antioxidant, heat resistance can be improved, and synergistic action with a light stabilizer can improve the light stabilizing effect.
 
Package: Packed in cardboard drum lined with plastic bag, net weight 25kg/drum, can also be designed according to customer requirements.
Storage: UV-absorbing agent UV-770 is non-toxic, non-flammable, non-explosive, non-corrosive, and has good storage stability.
