MEKP (Methyl Ethyl Ketone Peroxide) curing agents initiate radical polymerization in unsaturated polyester resins, enhancing production efficiency and mechanical strength. Our triple-grade system offers tailored reactivity for diverse manufacturing environments with UN 3105 Class 5.2 safety certification.
✅ Reaction Control: Adjustable gel time from 8 to 40 minutes
✅ Eco-Compliance: REACH Annex XVII & RoHS 3 certified
✅ Industrial Safety: Phlegmatized formulations prevent spontaneous decomposition
✅ Global Standardization: ISO 1523 leakage-proof packaging
