Application

* TRUELICHT UV 328 is a strong absorber of ultraviolet radiation in the 290~400 region and has a high degree of photostability - photochemical energy absorbed in the Ultraviolet region is dissipated as thermal energy.

* Features strong UV absorption, low initial color, good solubility in plasticizers and monomers, moderately low volatility, and excellent compatibility in a wide variety of substrates.

* Recommended for use in polyolefins, PVC, styrene homo and copolymers, ABS,acrylic polymers, unsaturated polyesters, thermoplastic urethanes, moisture cured polyurethanes, polyacetals,PVB, polyvinylbutyral, two component epoxies and urethanes,oil alkyds and thermosetting acrylic enamels.

* TRUELICHT UV 328 can also be used in Powder coatings,can be used in combination with phenolic &phosphite antioxidants, and HALS to optimize performance in outdoor use.

* For additional information please consult the Material safety Data Sheet.
