1,3-Dibutyl-2-thiourea Usage And Synthesis

Description	Dibutylthiourea is used in the vulcanization of rubber, in paints and glue removers as an anticorrosive, in phonecards as a component of the thermocoating sprayed over the optically read layer of the card. Crosssensitivity to other thiourea derivatives is possible.
Chemical Properties	white to light yellow crystalline powder
Uses	N,N'-Di-n-butylthiourea is used in vulcanization accelerator and corrosion inhibitors for metal treatments. It is used as leather, plastic and rubber auxiliary agents.
Uses	Dibutyl thiourea is an accelerator for mercaptan-modified chloroprene rubber; activator for ethylene-propylene-diene terpolymers and natural rubber; antidegradant for natural rubber latex and thermoplastic styrene-butadiene rubber.
Flammability and Explosibility	Notclassified
Contact allergens	Dibutylthiourea is used in the vulcanization of rubber, in paints, and glue removers as an anticorrosive, and in phonecards as a component of the thermocoating sprayed over the optically read layer of the card. Cross- sensitivity to other thiourea derivatives is possible.
