CAS No 153519-44-9 UV Absorber hydroxyphenyl triazine for high-performance coatings
Description
R-455 is a novel benzotriazole UV absorber (UVA)that contains a propane diol group.It can react with various hardeners such as isocy3-nates, melamine resins,and siloxanes.When used with polyurethane elastomers, R-455 reacts with isocyanates to form covalent bonds and becomes part of the polymer main chain.This completely solves the UVA migration issue that has plagued polyurethane manufacturers for many years.In Figure 1,2% R-455 MDI-basedTPUachieves ayellowing resistance level thatis a5 good as aliphat-icTPU after 168 hr QUV340 exposure.When a high-performance UV stabilization system is required,R-455 shows an excellent synergetic effect when combined with CG 1152,a reactive N-OR HALS,and CG 106,an oligomeric HALS,as shown in Figure 2.When used in a melamine baking enamel (Figure 4),R-455 has an excellent solvent extraction resistancewith an extraction rate <5%,while more than 99%of the additive-type UVA was extracted.Under ASTM-G154 accelerated aging tests,R-455 shows a performance 35 good as triazine-type UVA,as Shown in Figure 5.
Applications
1.PUD resin synthesis
2.2K-PU coating
3.Melamine baking enamel 4.Siloxane resin
5.TPU film/spinning,E-TPU
6.Medical/food contactapplication
Strengths of Chiguard”R-455
1.Low initial color
2.With OH reactive functional grou 3.Long-term weathering resistance
4.Migration resistance
5.Solvent extraction resistance 6.High heat resistance
