CATALYST

Catalyst is a crucial component used in the curing process of polyester and vinylester resins. As a hardener or catalyst, it plays a vital role in initiating and speeding up the chemical reaction that transforms the liquid resin into a solid, durable material. Typically, CATALYST is a solution of organic peroxides, most commonly methyl ethyl ketone peroxide (MEKP), which, when mixed with the resin, activates its polymerization process.
This hardener is essential in industries such as marine, automotive, construction, and manufacturing, where polyester and vinylester resins are commonly used for making composite materials, laminates, and various reinforced plastic products. By controlling the amount of CATALYST used, manufacturers can adjust the cure time and hardness of the final product, allowing for customized properties suited to specific applications.
