Peroxidvernetzte

Peroxidvernetzte, also known as peroxide-cured, refers to a type of adhesive or sealant that is cured using a peroxide-based curing agent. This curing process involves a chemical reaction between the adhesive and the peroxide, which results in the formation of a strong, durable bond. Peroxidvernetzte adhesives and sealants are commonly used in various industries, including automotive, aerospace, and construction, due to their excellent adhesion properties, chemical resistance, and durability.

The curing process of peroxidvernetzte materials typically involves the use of a catalyst, which initiates the chemical reaction between the adhesive and the peroxide. The catalyst can be a metal salt, such as cobalt or manganese, or an organic compound. The curing reaction is exothermic, meaning it releases heat, which can be beneficial in certain applications, such as in the bonding of composite materials.

Peroxidvernetzte adhesives and sealants are known for their high strength-to-weight ratio, making them ideal for use in lightweight structures. They are also resistant to a wide range of chemicals, including fuels, oils, and solvents, making them suitable for use in harsh environments. Additionally, peroxidvernetzte materials can be used to bond a variety of substrates, including metals, plastics, and composites.

However, peroxidvernetzte adhesives and sealants have some limitations. The curing process can be sensitive to temperature and humidity, which can affect the final properties of the adhesive. Additionally, the use of peroxide-based curing agents can be hazardous, requiring proper handling and disposal procedures. Despite these limitations, peroxidvernetzte materials remain a popular choice in many industries due to their excellent performance characteristics.
