BLS 292 is recommended in coating applications including coil coatings, automotive coatings, radiation curable coatings, paints, inks and wood stains. Coating systems in which BLS 292 is ideal include one and two-component polyurethanes, thermosetting and thermoplastic acrylics (physical drying), water borne acrylics, radiation curable acrylics, alkyds, and polyesters. BLS 292 can also be used in combination with UV absorbers to provide significantly enhanced performance. BLS 292 is also recommended in plastic applications, including styrenics, acrylics, polypropylene, polyethylene, unsaturated polyesters, polyurethane, elastomers, PVC, and PVB. The addition of antioxidants/process stabilizers is recommended for optimum performance in preventing thermooxidative degradation. Sulfur-containing phenolic antioxidants (BNX® 1035) may have a negative effect on the performance of BLS 292 and should be evaluated before use.
- Guidelines for Use
The recommended loading concentrations range between 0.5% and 2.0% depending on substrate, processing conditions, and long-term stability requirements. Exact loading must be determined by compositions of the specific polymer system. The dispersion of BLS 292 in waterborne coatings may be facilitated by dilution with a water miscible solvent. In plastics, recommended use levels range between 0.1 and 1.0%. The exact amount to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use
