Peroxide hardener

In surface technology, the peroxide hardener plays an important role in the curing of materials such as polyester resin. Peroxide hardeners are chemical compounds that serve as initiators for the polymerization of resins, especially unsaturated polyester resins.

The functional principle of peroxide hardeners is based on their ability to initiate radical reactions. As soon as the peroxide hardener is mixed with the resin, it begins to decompose and forms reactive radicals. These radicals then initiate the polymerization reaction in the resin, causing the molecules to cross-link and the material to cure.

Choosing the right peroxide curing agent depends on various factors, including the type of resin, the desired curing time and the required mechanical properties of the end product. Different peroxide hardeners have different decomposition rates and activation temperatures, which makes their application versatile and allows the curing conditions to be adjusted according to requirements.

Peroxide curing agents are used in a variety of surface coating applications, including the manufacture of glass fiber reinforced plastics (GRP), composites, molded parts, boats, tanks and more. With their ability to cure quickly and efficiently, peroxide hardeners contribute significantly to the productivity and quality of surface coating processes.
