Application:
>Tinuvin 770 is A Low molecular weight hindered amine light stabilizer (HALS).
>UV 770 prevents ultraviolet degradation in polypropylene, polystyrene, ABS, polyurethanes, polyacetals, and polyamides. It provides outstanding long-term stability by a radical trapping mechanism similar to that of hindered phenols. Very effective for articles with a high surface area such as films and tapes.
>The recommended concentrations of tinuvin 770 range is between 0.1 % and 1.0 %, depending on the substrate, processing conditions and application.
Handing and Safety:
>Not intended for use in applications that come in contact with food or in products which may come in contact with mucous membranes or abraded skin or be implanted into the body.
>For additional handing and toxicological information, please consult us for Maternal Safety Date Sheet.
