Characteristics

UV-1577 represents a new class of UV absorber exhibiting very low volatility and good compatibility with a variety of polymers, co-additives and resin compositions. It allows polycarbonates and polyesters to achieve a higher resistance to weathering than conventional benzotriazole UV absorbers.

Application

UV-1577 applications include polyalkene terephthalates and naphthalates, linear and branched polycarbontes, modified polyphenylene ether compounds, and various high performance plastics.The use of UV-1577 is indicated in polymer blends & alloys, such as PC/ABS, PC/PBT, PPE/IPS, PPE/PA and copolymers as well as in reinforced, filled and/or flame retarded compounds, which can be transparent, translucent and/or pigmented. Its very low tendency to chelate allows UV1577 formulations in polymers containing catalyst residues.

benefits

UV-1577 is particularly suitable for processing and aging conditions where high loadings, low volatility and good compatibility are required. Such requirements are especially critical for complex moldings, fibers, plain and corrugated sheets, twin wall sheets, thin films, co-injected or coextruded semi-finished parts.Depending on equipment, processing conditions, and polymer types, UV-1577 allows direct twolayer co-extrusion of sheets without the use of a neutral third top layer to prevent sublimation and/or deposits generated by the thin, highly UVA-loaded second layer. Moreover, its very high UVscreen actitivity allows the use of lower concentrations than with traditional UV absorbers. This may be of particular importance when using UV-1577 in high concentration applications.
