| | 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. | | 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 | 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. |
