BLS 1622


BLS 1622 (65447-77-0) is a high molecular weight hindered amine light stabilizer.  BLS 1622 has minimal interaction with co-additives such as pigments and other stabilizers and thus is highly effective in systems using carbon black and pigmented systems.  Secondary effects as an antioxidant are realized in the long-term heat stability of polyolefin systems.  Areas of application include polyethylene, polypropylene, unsaturated polyester, styrenics, acrylics and vinyl polymers.
