Antiozonant compounds are chemicals that help protect materials from damage caused by ozone (O3) exposure. They are commonly used in coatings, elastomers, and other products to prevent degradation of rubber, plastics, and other organic materials in the presence of ozone.

Ozone can cause materials to crack, brittle, and deteriorate rapidly, leading to reduced flexibility, strength, and lifespan. Antiozonant compounds are added to these materials to inhibit this degradation process and extend their service life. The mechanism of action of antiozonant compounds typically involves a redox reaction, where they scavenge ozone molecules, neutralize free radicals, and reinforce molecular bonds, thus inhibiting oxidative degradation.

The most common antiozonant compounds include synthetic and naturally occurring substances such as hindered phenols, amines, thioureas, and silicon-based additives. They are often used in applications where rubber, plastics, or other materials are exposed to high ozone levels, such as in the automotive industry, where tires and belts are prone to ozone-induced degradation.

Effective antiozonant compounds must possess properties such as good compatibility with the material being protected, high stability, non-toxicity, and low volatility. Their selection and formulation depend on the specific application and industry, and often require detailed testing and evaluation to ensure optimal performance and protection against ozone-induced degradation. Overall, antiozonant compounds play a crucial role in preserving the integrity and longevity of materials, ensuring safe and reliable operation of equipment, vehicles, and other systems that are exposed to ozone-rich environments.
