Application: UV- 5411 is a unique photo stabilizer that is effective in a variety of polymeric systems: particularly in polyesters, polyvinyl chlorides, styrenics, acrylics, polycarbonates, and polyvinyl butyal. UV- 5411 is especially noted for its broad range UV absorption, low color, low volatility, and excellent solubility. Typical end-uses include molding, sheet, and glazing materials for window lighting, sign, marine and auto applications. Specialty applications for UV- 5411 include coatings (particularly themosets where low volatility is a concern), photo products, sealants, and elastomeric materials.
