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. | [LogP]

| [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. | [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. | [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]
