Anti-gas agents generally do not belong to dangerous chemicals, such as common vitamin C is an antioxidant, but it can not be excessive, as long as excessive will be toxic, the antioxidant BHT invented by Bayer company in Germany is widely used for industrial purposes.

Antioxidants can prevent the oxidation of easily oxidized substances, antioxidants can improve the life of the paint, so that the paint as much as possible to maintain its initial high performance, paint, adhesive, sealant or oil. The components in the gas may be degraded by gasification during production, storage, transportation, use and final use.

Degradation is due to gasification or UV, vanadiation is mainly due to city gas or regas caused, it can occur under Beijing temperature or high temperature conditions, in the condition of increasing the temperature of the anti-gas agent can reduce the gasification and pergas free “formation and pergas free radicals can lead to the formation of a group of color or make the coating performance worse.

For the powder coating, the inhibitor can reduce the thermal peak decomposition of the resin, make the coating yellow, and reduce the mechanical and chemical properties of the paint film. Usually, the phenolic compounds are used as the main anti-gas agents, the organic acid compounds are sometimes used as trapping antioxidants, and the positive phenolic antioxidants are effective killers of free radicals. However, under the condition of the presence of burning gases, the chemical properties of the coating can be reduced. Antioxidants are easy to turn red, Ammanic antioxidants can be used as peroxide decomposing agents, under high temperature or curing conditions, to protect the paint from oxidation, enzyme compound antioxidants are carbon or oxygen free radical quenching agents, can inhibit the occurrence of automatic oxidation, high-performance, phenolic free compound antioxidants, the sulfonic acid and internal vinegar compound, A synergistic effect can be created, that is, the combination of different types of antioxidants can meet the requirements of heat and processing at the same time.

Antioxidants can slow down the automatic oxidation reaction rate of polymer materials, antioxidants in addition to plastics, rubber applications, but also widely used in petroleum products, oils and food industry, to prevent fuel oil, lubricating oil acidity and viscosity rise and grease, meat and feed rancidity.
