• 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.
• 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. 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.
