TBC / tert-Butyl Catechol Compatibility with Rubber O-Rings & Gaskets

Tert-Butyl catechol, often referred to as TBC, is an aromatic organic compound with the molecular formula C10H14O2. It typically appears as a white to tan crystalline solid and is widely recognized for its performance as a polymerization inhibitor and antioxidant. TBC is added to reactive monomers to control free radical activity and help maintain chemical stability during storage, transport, and processing. A primary function of tert-butyl catechol is preventing unwanted polymer formation in monomers such as butadiene, styrene, and vinyl acetate. By slowing spontaneous polymerization, it helps reduce safety risks, preserve material quality, and extend shelf life. In addition, TBC is incorporated into selected resin systems, coatings, and adhesive formulations to enhance oxidative resistance and maintain consistent product performance over time. Because tert-butyl catechol may present health hazards if inhaled, ingested, or absorbed through skin contact, appropriate storage and handling procedures are essential. It should be kept in properly labeled containers and handled in well-ventilated environments using suitable personal protective equipment. When managed according to recommended safety practices, TBC remains an important stabilizing additive in the production and storage of monomers and polymer-based materials across multiple industrial sectors.
