Chiguard® 5400WB CAS 153519-44-9 UV Absorbers UVA Light Stabilisers
CAS No 153519-44-9 UV Absorber hydroxyphenyl triazine for high-performance coatings
Description
water-borne coatings have received huge demand as society and governments put more pressure on
environmental protection such as VOC limit Various
new water-borne resins have been developed to meet the market demand.Likewise,water-borne UVAs have
become available with a broader range of products. Chiguard5530 is the frst water-borme UVA as it is easily emulsified.However,it fails in poor storage stability with 2K PUD systems as shown in Figure 1 where precipitation was observed in PUD in the front jar.Chiguard5530 also shows low stability against rain washing.
Two new emulsified liquid UVAs,Chiguard5582WB Chiguard5400WBandonewater-borneHALS Chiguard 101WB are introduced here.These three products feature improved resin compatibility and coatings storage stability across all water-borne systems, including leading edge 2K PUD systems.The Chiguardwater-borne series easily mix into formulas (Figure 2)without any pre-emulsification like Chiguard5530.These products remain stable and in solution unlike water-borne UVAs from previous generation(Figure 1).
All three water-borne UVAs enjoy high stability against rain washing which makes exterior coatings more durable(Figure 3).Other advantages include: high initial gloss,high inter-miscibility among three water-borne UVAs and high miscibility with a wide
