EGECat® CobaltOct promoters are used to accelarate the decomposition of peroxides at room temperature to crosslink unsaturated polyester resins (UPR).
EGECat® CobaltNeo promoters are recommended during transition period of REACh as the water solubility, thus bioavailability is much lower than EGECat® CobaltOct family.
EGECat® XB or EGECat® XC are the different types of cobalt based accelerators . The main difference is that they contain a synergistic promoter which improves the activity of cobalt and gives a better and lighter colour on the final application. Common usage levels are between 0.02 to 0.05 % based on metal on UPR.
