BLS® 292 is a liquid hindered amine light stabilizer (HALS). It provides outstanding light stability to many industrial and automotive coatings, as well as providing long-term stability to a wide variety of polymeric systems including styrenics, acrylics, polyethylene, polypropylene, and polyurethane. As a liquid, BLS® 292 blends easily and disperses completely resulting in lower loading requirements, virtually eliminating the particle dispersion problems associated with traditional powder HALS. The liquid form also allows for outstanding compatibility with a wide variety of coating systems, including waterborne and UV curable coatings.

Applications: BLS® 292 is a sterically hindered amine light stabilizer offering excellent protection against ultraviolet degradation. BLS® 292 is effective in coating applications including coil coatings, automotive coatings, radiation curable coatings, paints, inks and wood stains. BLS® 292 is highly effective in coatings based on a variety of binders such as: one and two-component polyurethanes; thermosetting and thermoplastic acrylics (physical drying); water borne acrylics; radiation curable acrylics; alkyds and polyesters. In coating applications BLS® 292 can also be used in combination with other light stabilizers to provide significantly enhanced performance. Additionally, BLS® 292 is an efficient light stabilizer for use in plastic applications. Specific polymeric systems being styrenics, acrylics, polypropylene, polyethylene, unsaturated polyesters, polyurethane, elastomers and vinyl monomers (PVB and PVC). For plastic applications the addition of antioxidants/process stabilizers is recommended for optimum performance in preventing thermo-oxidative degradation. Sulfur-containing phenolic antioxidants (BNX® 1035) may have a negative effect on the performance of BLS® 292 and should be evaluated in preliminary tests before use.

Advantages:

• Excellent miscibility

• Low volatility

• Compatible with a wide variety of systems

• Highly effective in heavily pigmented systems

• Lower loading requirements as a result of complete dispersion

• Synergistic performance with other light stabilizers (coatings) and antioxidants (plastics)

• Extends life time of coatings by minimizing defects such as loss of gloss and cracking
