What is 1,3-Dibutyl-2-thiourea?

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

The Uses of 1,3-Dibutyl-2-thiourea

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.

The Uses of 1,3-Dibutyl-2-thiourea

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.
