Hostavin® VSU powder is an Oxalanilide UV absorber, a low volatile polar substance with good heat stability. It is resistant to discoloration with metal ions, e.g. from polymerization catalyst residues, fillers or from contact surfaces. Hostavin® VSU powder absorbs the UV light especially in the UV-B range, and is therefore a stabilizer of choice for combinations with optical brighteners and for UV curing systems.
