Anwendungen & Verwendung
Beschreibung
Tetramethylthiuram disulfide is a rubber chemieal, an accelerator of vulcanization. It represents the most commonly positive allergen contained in the "thiuram mix". The most frequent occupational categories are the metal industry, homemakers, health services and laboratories, building industries, and shoemakers.
Verwenden
Tetramethylthiuram disulfide is used as fungicide; bacteriostat; pesticide; rubber vulcanization accelerator; scabicide; seed disinfectant; animal repellent; insecticide; lube-oil additive; wood preservative; in antiseptic sprays; in the blending of lubrieant oils; used against Botrytis, rusts and downy mildews; seed dressing against "damping off' and verticillium wilt; ethanol antagonist and deterrent in mixtures of the methyl, ethyl, propyl, and butyl derivatives; antioxidant in polyolefin plastics; peptizing agent in polysulphide elastomers; in soaps and rodent repellents; nut, fruit, and mushroom disinfectant.
