    Cadox L-30a is a special purpose catalyst for promoted unsaturated polyester and vinyl esters. It is used in place of Cadox L-50a varieties (Clear, RED and VR) where lower concentrations are needed as seen in warm summer months. Like all L-50a or L-30a varieties, it contains a low hydrogen peroxide content to minimize gassing and a high dimer content to maximize cure of polyester and vinylester resins.  Additional end-use information is available in Nouryon’s application brochures.
