Utere
Hoc productum est absorbens UV magni ponderis molecularis classis hydroxyphenybenzotriazoli, stabilitatem lucis egregiam erga varietatem polymerorum in usu ostendens.
Summa efficacia est pro polymeris quae plerumque altis temperaturis tractantur, ut polycarbonate, polyesteris, polyacetalo, polyamidis, polyphenyleni sulfido, polyphenyleni oxido, copolymeris aromaticis, polyurethano thermoplastico et fibris polyurethanis, ubi amissio UVA non toleratur, necnon pro polyvinylchlorido, styreni homo- et copolymeris.
