UV326 est absorber UV 300-400nm, cum bona luce stabilizationis effectus, lumen ultraviolaticum in energiam convertens per actionem photochemicam; productum efficaciorem habet effusio bandae longae, convenientiae bonae cum polyolefino, volatili et humili ionizatione inhibitionis; Productum bonum habet resistentiam alcalini, nec color mutabitur propter metalla. Ob altissimam ionizationem constantem, agente metallo siccitate, catalyst in influentiam suam humilem; in productis velit, cum phenolico antioxidante et phosphite antioxidante adhiberi potest.
Maxime adhibetur in polyvinyl chloride, polystyrene, resina unsaturata, polycarbonate, polymethylo methacrylato, polyethylene, ABS resina, epoxy resina et sic in aliis.
Commendatur moles: 0,1% -1.0%, specifica quantitas secundum applicationem testium emptoris determinatur
Referta in 20 vel 25 Reg / lobortis.
Repone in loco frigido, sicco et ventilato; ne solis directum.
