BLS® 1622 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.

Applications: BLS® 1622 is a polymeric HALS favorable for applications where low volatility and a low melting range are required. BLS® 1622 is highly effective in pigmented systems and systems using carbon black. Recommended substrates include: polyethylene, polypropylene, unsaturated polyester, styrenics, EVA, polyacetals, polyurethane, acrylics and engineered plastics. Typical end use applications include adhesives, sealants, elastomers, fibers and films. BLS® 1622 can be combined with other Mayzo HALS or UV absorbers to attain synergistic effects.

Advantages:

• Excellent performance in pigmented systems

• Secondary effects of long-term heat stability

• Low volatility

• Compatibility with other stabilizers
