UV327 potest fortiter haurire 300-400nm ultraviolacum lumen, bonum chemicae stabilitatis, humilis volatilis, boni compatibilitas cum polyolefin, humilis volatilis, humilis toxicitas, non flammabilis, nulla corrosio, bonum repono firmitatis, ac synergia significante cum DLTDP (PS800). Maxime apta est polymerorum, quae valde sensitiva sunt ad radiorum ultraviolaticum diutum (ex. gr. polyimidites, sulfides polyphenyl) et applicationes quae transmissionem requirunt humilem ad radiorum ultravioletum longam (eg, lens optica).
Maxime adhibetur in polyvinyl chloride, polystyrene, resina insaturata, polyurethane, polymethylo methacrylato, polyethylene, ABS resina, fibra polypropylene, fuco, agente fuco, stipticis aliisque polymerorum ac multis aliis agris.
Referta in 20 vel 25 Reg / lobortis. Vel referta ut per elit elit.
Repone in loco frigido, sicco et ventilato; ne solis directum.
