| Structure |  |
| Description | Tiangang® BW-10LD (622) is a highly effective radical scavenger belonging to the Hindered Amine Light Stabilizers (HALS) family of stabilizers. It is a polymeric HALS with low melting range, which is very suitable for use in polypropylene, polyethylene, polyurethane, metaformaldehyde, polyamine and polyester. Tiangang® BW-10LD typically demonstrates reduced interaction with co-additives such as pigments or other stabilizers and is an excellent stabilizer for systems containing high loadings of carbon black. |
