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.
