Uvanone 3C is an UV filter, belonging to benzophenone derivatives; its absorption capacity ranges from 260 to 350 nm with two maxima of absorbance at 288 and 328 nm.
Uvanone 3C does not absorb in the visible region (Figure 1). Uvanone 3C has an excellent solubility in aromatic solvents and in some polar solvents, e.g. ketone. It has a good solubility in plasticizers, it is slightly soluble in alcohols where as is practically insoluble in water.

Uvanone 3C is compatible with different polymeric materials, particularly with polyolefins, it is thermally stable and
is compatible with a broad range of additives, normally used in polymer formulations.

Uvanone 3C shows relevant synergistic effects in combination with HALSs and Nickel quenchers.

APPLICATIONS

As a good UV filter, Uvanone 3C is recommended for the protection of polymers and polymer resins from light

• Polypropylene

• Olefin copolymers (EP, EPDM, EPR, EVA)

• Rigid and elastic PVC

• Polystyrene and styrenic copolymers

• Polyesters

• Epoxy resins
