FEATURE AND APPLICATION

* JADEWIN 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 curedpolyurethanes, polyacetals, polyvinylbutyral, two component epoxies and urethanes,oil alkyds and thermosetting acrylic enamels.

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