Brief Introduction
In industrial applications, dilauroyl peroxide is used as a curing agent in the production of thermoset plastics, elastomers, and other polymer-based materials. It is particularly effective in initiating the polymerization of unsaturated polyester resins and vinyl ester resins, contributing to the formation of strong and durable composite materials.
Dilauroyl peroxide is also utilized in the production of adhesives, coatings, and other polymer-based products where the initiation of radical polymerization is required.
It’s important to note that dilauroyl peroxide, like other organic peroxides, should be handled with care and in accordance with safety guidelines due to its potential hazards and reactivity.
