DIC Tertiary Butyl Catechol
DIC tertiary butyl catechol (TBC) is a highly specialized polymerization inhibitor for products such as butadiene, styrene, and other unsaturated hydrocarbons. It also functions as an antioxidant and stabilizer for polyethylene, silicone rubber, heptane, vinyl pyridine, and dicyclopentadiene. In stannic tin catalysts and urethane foams, TBC is used as a chelating agent. TBC is a free radical scavenger, which can extend gelation time. It will not discolor styrene monomers, nor will it crystallize over time as will various hydroquinone type inhibitors.
