Characterization:

UV- 770 is a hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes.

Application:

UV- 770 is recommended to be used in polypropylene, impact modified PP (TPO), EPDM,polystyrene, impact poystyrene, ABS, SAN, ASA and polyurethanes and is also effective in polyamides and polyacetals.

Features: UV-770 is a low molecular weight hindered amine light stabilizer that provides excellent light stability for thick sections and films in the recommended substrates. Benefit of using UV-770 is the high light-stabilizing performance, particularly in PP thick sections. It has broad compatibility and can be easily dispersed. Compared to conventional UV-absorbers, the effectiveness of UV-770 is less dependent on the polymer’s thickness. For this reason the use of UV-770 also provides good light stability in articles with higher specific surface, e.g. films and tapes. Combined with other HALS UV-770 is part of other synergistic blends, e.g. UV-791

Guidelines:

The recommended concentrations range between 0.1% and 0.5%, depending on the substrate, processing conditions and application. The optimum level is substrate and application specific. Extensive performance data of UV-770 in various substrates and for various applications is available upon request.

Packing:

In 25kg net pp cartons on pallets or 20kg bags, 500kg (carton) per pallet or 500kg (bags) per pallet or as required or 110 pound fibre drum on pallet with shrink film. Palletizing is wrapped and film shrunk

Loading capacity: 10mt per 20’FCL

Packaging & Shipping

UV Light stabilizer UV-770 is available in powder form in a 25 kg carton net weight, with an inner PE liner.
