Description

Antozite 2 CAS NO 139-60-6 is a high-performance chemical additive widely recognized for its role as a polymerization inhibitor and antioxidant. This compound is critical for ensuring the stability and shelf-life of sensitive materials during storage, transport, and processing. It is an essential component for manufacturers in the polymer, petrochemical, and specialty chemical industries who require reliable protection against premature degradation and unwanted polymerization.

Application

• Primary use as a polymerization inhibitor in the production and storage of monomers like styrene, butadiene, and acrylic esters.
• Acts as an effective antioxidant in lubricants, fuels, and hydraulic fluids to prevent gum and sludge formation.
• Stabilizer in the manufacture of synthetic rubbers and elastomers to control curing and cross-linking processes.
• Used in adhesive and resin formulations to enhance pot life and storage stability.
• Protective additive in the petrochemical industry for feedstock streams susceptible to thermal or oxidative degradation.
• Employed in research and development for studying free-radical scavenging mechanisms.
