1,3-Dibutyl-2-thiourea Chemical Properties, Uses, Production
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.
Definition
ChEBI: N,N'-dibutylthiourea is thiourea in which each nitrogen carries a butyl substituent. It has a role as an allergen.
Flammability and Explosibility
Not classified
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.
